[PATCH i-g-t 1/3] tests/xe_exec_compute_mode: Make lr-mode-workload spinner preemptible

["Thomas Hellström" <thomas.hellstrom@linux.intel.com>]

Enable preemption in the xe_spin used by lr-mode-workload by passing
.preempt = true to xe_spin_init_opts(). This allows the workload to be
preempted during the 30s stress run, which is needed to test LR mode
behavior under preemption (e.g. during suspend/resume).
