AUTOFS: allow removing entries from hash table

There is a timed desctructor in the autofs responder that, when the
entry timeout passes, removes the autofs map from the hash table while
the map is freed. This patch adds a hash delete callback so that if the
map is removed from the hash table with hash_delete, its hash table
pointer will be invalidated. Later, when the entry is being freed, the
destructor won't attempt to remove it from the hash table.
