[PATCH] drm/xe/guc_submit: improve schedule disable error logging

[Matthew Auld <matthew.auld@intel.com>]

A few things here. Make the two prints consistent (and distinct), print
the guc_id, and finally dump the CT queues. It should be possible to
spot the guc_id in the CT queue dump, and for example see that host side
has yet to process the response for the schedule disable, or see that
GuC is yet to send it, to help narrow things down if we trigger the
timeout.
