hack in RLC AM to avoid a race
Here is the problem:
UE comes. SRB2 is configured via message to RRC.
At some point the RLC AM is created but not configured yet.
At this moment (I think) MAC calls mac_rlc_status_ind
which calls this function. But the init was not finished yet
and we have a crash below when testing mem_block != NULL.
The "solution" is to test if rlc->input_sdus is NULL.
This is a very dirty hack. I would say the solution
is to use proper locking mechanism because RLC is used
by two threads: PHY/MAC on one hand and RRC on another
hand (I think).
