Nirmoy Das 37a1cf288e drm/xe/ufence: Wake up waiters after setting ufence->signalled
If a previous ufence is not signalled, vm_bind will return -EBUSY.
Delaying the modification of ufence->signalled can cause issues if the
UMD reuses the same ufence so update ufence->signalled before waking up
waiters.
