ANDROID: sdcardfs: Don't bother deleting freelist
There is no point deleting entries from dlist, as that is a temporary list on the stack from which contains only entries that are being deleted. Not all code paths set up dlist, so those that don't were performing invalid accesses in hash_del_rcu. As an additional means to prevent any other issue, we null out the list entries when we allocate from the cache.
