[PATCH] os/inputthread: Force unlock when stopping thread.

[msrb at suse.com]

From: Michal Srb <msrb at suse.com>

The inputthread is kept locked all the time while X server's VT is not active.
If the X server is terminated while not active, it will be stuck forever in
InputThreadFini waiting for the thread to join, but it wouldn't because it is
locked.

This fixes the X server termination while its VT is not active. I think it
should be safe to force unlock it from InputThreadFini - X server is
terminating and nothing else should race there, but I am not completely sure.
