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

Pedro Alvarez fbcffb84bd Check if RLC is suspended before transmiting PDCP SDU. 
This was done to avoid integrity issues, when the UE's RRC erroneously sent
measurement reports while the re-establishment was already in progress.

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