[PATCH i-g-t 2/3] tests/intel/xe_exec_reset: Add checks for hanging queue wait_ufence return

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

There is a 3 second wait user fence timeout for the compute mode
variants of this test. Instead of just skipping the wait altogether,
let's make sure this does in fact return -ETIME as expected there.

Also add the i == 0 cases for legacy and compute path for the actual
data checks to stay consistent and to be a little more explicit
about what we're checking there.

This also let's us add a little more detail to the cases in some
planned changes around hanging multi queue secondary queues.
