Don't grab the server when unmanaging the screen

Browse Source 
There's no obvious reason for grabbing the X server when unmanaging
a screen - the only race conditions a server grab solves are those
related to querying and then acting on the results of the query.

Our shutdown sequence is correctly ordered according to the ICCCM -
we first unselect on the root window, and then we destroy the
window owning WM_S<n> so removing the grab should not cause any
problems when we are being replaced with another window manager.
