rlcmac: rlc_window_dl: Fix RBB generation

We want to do mod sns on the BSN, not on the boolean returned by gprs_rlcmac_rlc_v_n_is_received(). This is a typo which occurred while porting the code from osmo-pcu.git void gprs_rlc_ul_window::update_rbb(char *rbb), where the following line is used: """ if (m_v_n.is_received((ssn()-1-i) & mod_sns())) """
