Memory bug fixes

Browse Source 
Several places where memory ownership was changed
and the original owner was not set to NULL. Also,
the transaction_identifier is now based on the
received dl_dcch_msg in the LTE UE. Still need to
fix the t_id for the NR UE. Also added comments for
RACH procedure in NR UE.
