window: Allow grab if the display focus is unset

Browse Source 
As per commit 040de396b, we don't try to grab when shortcuts are inhibited,

However, this uses the focus window assuming that it is always set, while this
might not be the case in some scenarios (like when unsetting the focus before
requesting take-focus-window to acquire the input).

So allow the button grab even if the focus window is not set for the display
