Make two invocations of svn_ra_get_locks() check for the documented error code
instead of also for the invalid error code that ra_serf returned.

* subversion/libsvn_client/info.c
  (svn_client_info4): Just check for the documented error.

* subversion/libsvn_client/status.c
  (reporter_finish_report): Just check for the documented error.
