evdev: Don't update xkb state with pressed keys on keymap change

Browse Source 
Doing so is unlikely to work reliably. Instead, switching the keymap
should be done at a time when no key is currently pressed down, but
let's leave that task to higher level code.

This allows us to remove key state tracking at yet another level in
the stack since higher level code likely already tracks this for other
purposes.
