From: Gustavo Padovan <gustavo.padovan@collabora.co.uk>
If userspace is running an synchronously atomic commit and interrupts the atomic operation during fence_wait() it will hang until the timer expires, so here we change the wait to be interruptible so it stop immediately when userspace wants to quit.
