drm/xe/oa: Check managed mutex initialization errors

Browse source

drmm_mutex_init() can fail while registering its managed cleanup action.
On failure, the reset path destroys the mutex, so continuing OA setup
leaves an unusable lock that later paths may acquire.

Return the error from per-GT OA initialization and abort device-wide OA
initialization if the metrics lock cannot be initialized.
