misc: remove debug print and fix wrong index accessing array

Before this MR, openair1/PHY/NR_TRANSPORT/nr_ulsch_llr_computation.c:
nr_ulsch_qam64_qam64():
    xmm3 = simde_mm256_max_epi16(bit_met_m5_p1, bit_met_m5_p1);

Should be instead:
    xmm3 = simde_mm256_max_epi16(bit_met_m5_p1, bit_met_m7_p1);
