drm/xe: Use local fence in error path of xe_migrate_clear
The intent of the error path in xe_migrate_clear is to wait on locally
generated fence and then return. The code is waiting on m->fence which
could be the local fence but this is only stable under the job mutex
leading to a possible UAF. Fix code to wait on local fence.
