drm/xe: Drop registration of guc_submit_wedged_fini from xe_guc_submit_wedge()

Browse source

xe_guc_submit_wedge() runs in the DMA-fence signaling path, where
GFP_KERNEL memory allocations are not permitted. However, registering
guc_submit_wedged_fini via drmm_add_action_or_reset() triggers such an
allocation.

Avoid this by moving the logic from guc_submit_wedged_fini() into
guc_submit_fini(), where wedged exec queue references are dropped during
normal teardown.
