bssgp: Fix bssgp_tx_fc_bvc parameter type
Currently large values for Bmax default MS get sliced since a uint16_t is used as the type of the corresponding parameter of bssgp_tx_fc_bvc. GSM 48.018, 11.3.2 which in turn refers to 11.3.5 specifies a maximum of 6MB (0xffff * 100). This commit changes the type to uint32_t to cover the full value range. Sponsored-by: On-Waves ehf
