Enforce op. quota file format for MDS too

  - check for OBD_FAIL_OBD_LLOG_SETUP fail_loc regardless ->lop_setup definition. This is required because
  after changes in mds_ost llog setup, which is now done on behalf of separate thread, we need to make
  llog_setup() fail in context of mds start thread to make the test actualy work. And those llogs which
  get initialized in mds start thread do not have ->lop_setup defined.
