[PATCH i-g-t 2/2] tests/intel/xe_pm_residency: Limit max usleep time to 50sec.

[Himal Prasad Ghimiray]

There may be an approximately 1-second delay between xe_exec and
xe_sched_job_run, which could result in the usleep duration exceeding IGT
timeouts. To address this, limit the maximum usleep time to 50 seconds
