mac80211: 160MHz with extended NSS BW in CSA

Browse Source 
[ Upstream commit dcf3c8fb32ddbfa3b8227db38aa6746405bd4527 ]

Upon receiving CSA with 160MHz extended NSS BW from associated AP,
STA should set the HT operation_mode based on new_center_freq_seg1
because it is later used as ccfs2 in ieee80211_chandef_vht_oper().
