Previously, the various rlc_*_ind() functions had a parameter to enable
the MAC to specify the max TB size that a subsequent call to the

this parameter from the rlc_*_ind() functions and makes the parameter
working that is already in the rlc_*_req() functions.

Fix also value passed to buffer_status in mac_rlc_status_ind

Initial implementation.

nr_rlc/nr_rlc_oai_api.c will need some clean rewrite at some point.

More testing is also needed.
