    wifi: cfg80211: handle 2x996 RU allocation in cfg80211_calculate_bitrate_he()
    
    [ Upstream commit bcbd771cd5d68c0c52567556097d75f9fc4e7cd6 ]
    
    Currently NL80211_RATE_INFO_HE_RU_ALLOC_2x996 is not handled in
    cfg80211_calculate_bitrate_he(), leading to below warning:
    
    kernel: invalid HE MCS: bw:6, ru:6
    kernel: WARNING: CPU: 0 PID: 2312 at net/wireless/util.c:1501 cfg80211_calculate_bitrate_he+0x22b/0x270 [cfg80211]
    
    Fix it by handling 2x996 RU allocation in the same way as 160 MHz bandwidth.
