[Why]
In GNOME Settings->Display the switching from mirror mode to single display
occasionally causes wait_for_completion_interruptible_timeout() to return
-ERESTARTSYS and fails atomic check.
[How]
Replace the call with wait_for_completion_timeout() since the waiting for
hw_done and flip_done completion doesn't need to worry about interruption
from signal.
