Remove MDL when delete operation fails with INVALID_MDLID error

Browse Source 
We can remove a data channel if error code Invalid MDLID is provided
in reply to a MD_DELETE_MDL_REQ. That error is provided only if the
MDL ID referenced is invalid. This shall be used when:
- A reserved or invalid value for MDL ID was used.
- The MDL ID referenced is not available (was never created, has
been deleted, or was otherwise lost),
- The MDL ID referenced in the Abort request is not the same value
that was used to initiate the PENDING state
