Use UL functions for Qm/R determination

During refactoring, the wrong functions and correspondingly tables have
been used to calculate UL TB size. Fix through correct functions.
This should fix these error messages:

3624774.778195 [MAC]    E (nr_get_Qm_dl:2034)             Invalid MCS table index 3 (expected in range [0,2])
3624774.778207 [MAC]    E (nr_get_code_rate_dl:2066)      Invalid MCS table index 3 (expected in range [0,2])
3624774.778211 [NR_MAC] E (nr_compute_tbs:63)             Error in compute TBS with a NULL input, returning NULL TBS

Fixes: 9449f777 ("Remove TBS table and recompute on demand")
