drm/amdkfd: Handle restart of kfd_ioctl_wait_events
When kfd_ioctl_wait_events needs to restart due to a signal, we need to
update the timeout to account for the time already elapsed. We also need
to undo auto_reset of events that have signaled already, so that the
restarted ioctl will be able to count those signals again.
This fixes infinite hangs when kfd_ioctl_wait_events is interrupted by a
signal.
