Shuicheng Lin 7ac3cae7a2 drm/xe/hw_engine: Fix double-free of managed BO in error path 
The error path in hw_engine_init() explicitly frees a BO allocated
with xe_managed_bo_create_pin_map() via xe_bo_unpin_map_no_vm().
Since the managed BO already has a devm cleanup action registered,
this causes a double-free when devm unwinds during probe failure.

Remove the explicit free and let devm handle it, consistent with
all other xe_managed_bo_create_pin_map() callers.

Fixes: 0e1a47fcab ("drm/xe: Add a helper for DRM device-lifetime BO create")
