Carlo Galiotto dcc2c1c694 rrc,nr: defer rem_user after msg3 timer expires 
This commits is to fix the issue of user removal from rrc_nr
after msg3 timer expires.
The issue was caused because the rrc_nr is accessing the ue object
after it gets removed from the users list in rrc_nr.
This commits defers the removal of the users, so there won't be any
access to invalid memory locations.

Fixes #3545

This was done to avoid integrity issues, when the UE's RRC erroneously sent

As errously sending PDCP PDUs on DRBs can cause issues as well, this was
disabled too.
