fix limited UL data throughput in do-ra mode
...
In case of noS1-mode, we initialize the 'logicalChannelBearer_exist' array element for the pre-configured DRB0 in function 'nr_l2_init_ue()'.
That array is indexed with the LCID.
For DRB0, the LCID is 4.
Unfortunately, the code incorrectly used the array at index 0.
Therefore, the UE sent neither scheduling requests nor buffer status reports, what resulted in extremely poor UL throughput.

fix typo in nr_slot_fep_init_sync()
...
This function is used during initial synchronization, only.
This typo leads to wrong computation of the OFDM symbol start within a slot, after PBCH decoding.
The result is a time offset and therefore a rotation in frequency domain for the initial PDCCH and PDSCH (SIB1) reception.
