drm/amd/display: Refine globallock.

Browse source

Switch to wait_for_completion_interruptible_timeout wait
since the lock is called from IOCTL context and can be
interrupted by a signal.

Global lock function might return EDEADLK or EINTR which
is not an error and just singals to user mode to restart
the call.
