    AUTOFS: remove all maps from hash if request for auto.master comes in
    
    https://fedorahosted.org/sssd/ticket/1592
    
    When a request for auto.master comes in, we need to remove all the maps
    from the lookup hash table. We can't simply delete the maps, because
    another request might be processing them, so instead the maps are
    removed from the hash table, effectively becoming orphaned. The maps
    will get freed when the timed destructor is invoked.
