drm/xe: Reduce LRC timestamp stuck message on VFs to notice

An LRC timestamp getting stuck is a somewhat normal occurrence. If a
single VF submits a job that does not get timesliced, the LRC timestamp
will not increment. Reduce the LRC timestamp stuck message on VFs to
notice (same log level as job timeout) to avoid false CI bugs in tests
where a VF submits a job that does not get timesliced.
