Andre Puschmann 3e5b40fd36 enb,rrc: fix compilation after freq point a has been removed from nr_carrier_t 
since absolute freq point a members have been removed from the srslte_nr_carrier_t
struct (they are now actual frequencies) the abs_point_a values are now in
the RRC cell structs

faluco fa351cd285 Rename functions that contain the unsafe word to nolock. 
The term "unsafe" does not clearly state that the function is not locking the shared date and it sounds "dangerous", so use a more explicit term.

Andre Puschmann 59e1bca3f5 rlc_am_lte: fix potential crash when attempting to resize tx queue 
under some circumstances it could happen that the RLC is configured
when SDUs are already being written to the queue. The resize
operation of the underlying container would fail in this case.

Make sure to empty the queue before doing the resize.

Andre Puschmann cc2d71183e ue,phy,nr: fix race condition when setting UL grant for Msg3 
the Msg3 UL grant requires the TTI in which the RAR has been received
to calcualte the correct timing. There was a race between PHY and Stack
thread.

This patch circumvents the issue by removing a PHY state member that only holds
the RAR Rx timing. In the new interface the RA proc passes the Rx TTI
to the PHY again when setting the UL grant so the PHY can calculate the
correct timing without any state.
