vlmemory/svm: fix client detach from svm region
Clients cannot know at svm region detach time if the shm backing files
have been recreated (e.g., if vpp restarts) and therefore should not try
to unlink them. Otherwise, terminating clients attached to previous
instantiations of a re-allocated region end up making the new instance
un-mappable by removing its backing file.
