[PATCH i-g-t 1/3] tests/intel/xe_exec_reset: Add a comment about return for syncobj wait

[Stuart Summers <stuart.summers@intel.com>]

Add a comment to the syncobj wait after a hanging submission
to indicate that even for the hang case, we expect the syncobj
wait to return successfully as opposed to the wait ufence case
where we only return successful if hardware did in fact execute
the batch through the MI_USER_INTERRUPT to satisfy the wait ufence.
