display: Unset grab_frame_action in meta_display_end_grab_op

Otherwise, if the user had moved the windows around using a mouse,
they can not be moved beyond the top edge of the primary monitor when
the tray needs to be brought up, . This is because
constrain_titlebar_visible looks at grab_frame_action and thinks that
the movement is being caused by the user trying to move the windows up
by grabbing the frame.

-/**
- * A list of screen keybinding information.
- *
- * Each action which can have a keystroke bound to it is listed below.
- * To use this file, define keybind() to be a seven-argument macro (you can
- * throw any of the arguments you please away), include this file,
- * and then undefine the macro again.
- *
- * (If you aren't familiar with this technique, sometimes called "x-macros",
- * see DDJ of May 2001: <http://www.ddj.com/cpp/184401387>.)
- *
- * This makes it possible to keep all information about all the keybindings
- * in the same place.  The only exception is the code to run when an action
- * is actually invoked; while we *could* have put that in this file, it would
- * have made debugging ridiculously difficult.  Instead, each action should
- * have a corresponding static function named handle_<name>() in
- * keybindings.c.
- *
- * The arguments to keybind() are:
- *   1) the name of the binding; a bareword identifier
- *              (it's fine if it happens to clash with a C reserved word)
- *   2) the name of the function which implements it.
- *              Clearly we could have guessed this from the binding very often,
- *              but we choose to write it in full for the benefit of grep.
- *   3) an integer parameter to pass to the handler
- *   4) a set of boolean flags, ORed together:
- *       BINDING_PER_WINDOW  - this is a window-based binding.
- *                             It is only valid if there is a
- *                             current window, and will operate in
- *                             some way on that window.
- *       BINDING_REVERSES    - the binding can reverse if you hold down Shift
- *       BINDING_IS_REVERSED - the same, but the senses are reversed from the
- *                             handler's point of view (let me know if I should
- *                             explain this better)
- *      or 0 if no flag applies.
- *
- *   5) a string representing the default binding.
- *          If this is NULL, the action is unbound by default.
- *          Please use NULL and not "disabled".
- *   6) a short description.
- *          It must be marked translatable (i.e. inside "_(...)").
- *
- * Don't try to do XML entity escaping anywhere in the strings.
