[igt-dev] [PATCH i-g-t] tests/intel: Do not error on -ECANCELED in xe_vm tests

[Jonathan Cavitt <jonathan.cavitt@intel.com>]

In the hammer class of unbind tests in xe_vm, a thread is created that
submits jobs to an exec queue initialized on a VM page that is later
unbound.  Because of the unbind, a job is timing out and marking the
exec queue as "banned", which causes all subsequent job submissions to
report as -ECANCELED (-125).

This is expected behavior.  The test should not fail when this is the
case, so use __xe_exec instead of the error-sensitive xe_exec in
hammer_thread, ignoring -ECANCELED and catching all other errors
manually.
