Fixes sporadic batch premature termination after sustained GPU workload
stress testing by hardening ticks_delta initialization/re-arming:
- initialize ticks_delta to ~0u in xe_spin
- reset ticks_delta to ~0u before fixed-duration batch submission
  in gem_wsim

Marcin Bernatowicz (2):
  lib/xe/xe_spin: initialize ticks_delta to ~0u
  benchmarks/gem_wsim: re-arm ticks_delta before batch submission
