xef is only valid if it's a job from userspace. For in-kernel jobs it
causes a NPD like below:
<4> [] RIP: 0010:xe_sched_job_create+0xbd/0x390 [xe]
...
<4> [] Call Trace:
<4> [] <TASK>
<4> [] __xe_bb_create_job+0xa2/0x240 [xe]
<4> [] ? find_held_lock+0x31/0x90
<4> [] ? xa_find_after+0x12c/0x250
<4> [] xe_bb_create_job+0x6e/0x380 [xe]
<4> [] ? xa_find_after+0x136/0x250
<4> [] ? __drm_dev_dbg+0x7d/0xb0
<4> [] xe_gt_record_default_lrcs+0x542/0xb00 [xe]
Since drm_file starts with 1 for the unique id, just use 0 for the
in-kernel jobs.
