Carlo Galiotto fb75cbaadc rrc: disable MAC bearers when RNTI gets updated 
When the RRC handles the C-RNTI CE to update the RNTI, all the bearers
associated with the new RNTI (that will no longer be used) need to be disabled.
This commit implements this.

this prepares for a change in which GTPU no longer writes into PDCP
directly but instead uses the stack as a wrapper.

of the LCID

The stack will know which PDCP entity (EUTRA or NR) is currently associated
with the EPS bearer ID and will forward the PDU accordingly.
