    Remove broken clean_hostname trace messages
    
    The trace messages in krb5int_clean_hostname were outputting the
    entire contents of the output buffer (mostly uninitialized garbage)
    into the trace log.  Since these messages were essentially redundant
    with messages in the callers, and were arguably at too low of a level
    to begin with, simply remove them.
    
    (cherry picked from commit d5aac5c1a010410e79cce4219e618d9ce27d8621)
    
    ticket: 7459
    version_fixed: 1.11
    status: resolved
