[PATCH 1/2] drm/xe/gsc: Fix double-free of managed BO in error path

[Shuicheng Lin <shuicheng.lin@intel.com>]

The error path in xe_gsc_init_post_hwconfig() 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: 2e5d47fe7839 ("drm/xe/uc: Use managed bo for HuC and GSC objects")
