Following up on r1553274, revert an libsvn_ra_serf internal api change as
the 'return status errors at the end of the request' fix made this change
unnecessary.

* subversion/libsvn_ra_serf/property.c
  (svn_ra_serf__deliver_props): Don't set no_fail_on_http_failure_status.

* subversion/libsvn_ra_serf/ra_serf.h
  (svn_ra_serf__deliver_props): Revert documentation change.

* subversion/libsvn_ra_serf/replay.c
  (svn_ra_serf__replay_range): Don't set flag to default value.

* subversion/libsvn_ra_serf/update.c
  (fetch_file): Don't set flag to default value.
