    sutils: fix file_name_lookup_carefully
    
    file_name_lookup_carefully is like file_name_lookup but tries hard to
    avoid starting any passive translators while doing the lookup. The
    callback contains code to get a new handle to the root if it
    encounters a translator, but this code was not being executed if the
    node had no record of an passive translator, just an active one.
    
    Fix the callback by dropping the test for a passive translator. AIUI
    the current check for a passive translator makes no sense, as the code
    is supposed to fail on encountering a passive translator.
    
    This fixes lookups inside translators that have no passive
    translator. For example if /run is a tmpfs started only as active
    translator, touch /run/lock && mount tmpfs -t tmpfs /run/lock -o
    size=5M would fail.
    
    * sutils/clookup.c (lookup): Drop the test for an passive translator.
