drm/nouveau: fence: fail to emit when fence context is killed
The new VM_BIND UAPI implementation introduced in subsequent commits
will allow asynchronous jobs processing push buffers and emitting
fences.
If a fence context is killed, e.g. due to a channel fault, jobs which
are already queued for execution might still emit new fences. In such a
case a job would hang forever.
To fix that, fail to emit a new fence on a killed fence context with
-ENODEV to unblock the job.
