drm/panfrost: Kill in-flight jobs on FD close
If the process who submitted these jobs decided to close the FD before
the jobs are done it probably means it doesn't care about the result.
v5:
* Add a panfrost_exception_is_fault() helper and the
DRM_PANFROST_EXCEPTION_MAX_NON_FAULT value
v4:
* Don't disable/restore irqs when taking the job_lock (not needed since
this lock is never taken from an interrupt context)
v3:
* Set fence error to ECANCELED when a TERMINATED exception is received
