Subject: REPOST patch 25/38: SERVER: wipe out all evidence in fh_put()

When a filehandle is cleared with fh_put(), wipe out all traces by
clearing ->fh_pre_saved and ->fh_post_saved.  This prevents
fill_post_wcc() from complaining if the filehandle is later reused.
(This could happen to CURRENT_FH if, for example, LOOKUP LOOKUP
occurs in a COMPOUND.)
