[PATCH] drm/xe/configfs: Free ctx_restore_mid_bb in release

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

ctx_restore_mid_bb memory is allocated in wa_bb_store(), but
xe_config_device_release() only frees ctx_restore_post_bb.

Free ctx_restore_mid_bb[0].cs as well to avoid leaking the allocation
when the configfs device is removed.

Fixes: b30d5de3d40c ("drm/xe/configfs: Add mid context restore bb")
