mirrors: fix read_only_volume_list

If a mirror LV is listed in read_only_volume_list, it would
still be activated rw.  The activation would initially be
readonly, but the monitoring function would immediately
change it to rw.  This was a regression from commit

fade45b1d14c mirror: improve table update

The monitoring function needs to copy the read_only setting
into the new set of mirror activation options it uses.
