[ Upstream commit 6ae24344e2e3e12e06f7b382af4bba2fd417b2ff ]
The purpose here is to allow to optimize exec_queue_set_job_timeout() in follow-on patch. Currently it does q->ops->set_job_timeout(...). But we'd like to apply exec_queue_user_extensions much earlier and q->ops cannot be called before __xe_exec_queue_init().
It will be much more efficient to instead only have to set q->sched_props.job_timeout_ms when applying user extensions. That value will then be used during q->ops->init().
