 Description   

We currently convert MODE_IX DB lock requests to any admin DB to a MODE_X DB lock request here in the DBLock constructor.

This should no longer be needed with the new finer grained locking. It should be investigated what lock conversions auth code may still need, if any, on the collection locking level. And the DB lock MODE_IX conversion to MODE_X should be removed.
