MCOL-4303 UPDATE..SET using another table is not updating

Browse Source 
The change for MCOL-4264 erroneously added the "lock_type" member
to cal_connection_info, which is shared between multiple tables.
So some tables that were opened for write erroneously identified
themselves as read only.

Moving the member to ha_mcs instead.
