    trans/fakeroot: fix cached node retrieval on lookup
    
    When a client finds a node from the hash table, it could happen that
    another thread is still holding one reference on it before the current
    thread has acquired its own. Simply checking for a non zero refcount isn't
    enough, the new client must atomically acquire its own reference.
    
    * trans/fakeroot.c (netfs_S_dir_lookup): Find and acquire node reference
    while holding netfs_node_refcnt_lock.
