ath11k: enable IEEE80211_VHT_EXT_NSS_BW_CAPABLE if NSS ratio enabled
When NSS ratio enabled reported by firmware, SUPPORTS_VHT_EXT_NSS_BW
is set in ath11k, meanwhile IEEE80211_VHT_EXT_NSS_BW_CAPABLE also
need to be set, otherwise it is invalid because spec in IEEE Std
802.11™‐2020 as below.
Table 9-273-Supported VHT-MCS and NSS Set subfields, it has subfield
VHT Extended NSS BW Capable, its definition is:
Indicates whether the STA is capable of interpreting the Extended NSS
BW Support subfield of the VHT Capabilities Information field.
dmesg have a message without this patch:
ieee80211 phy0: copying sband (band 1) due to VHT EXT NSS BW flag
It means mac80211 will set IEEE80211_VHT_EXT_NSS_BW_CAPABLE if ath11k not
set it in ieee80211_register_hw(). So it is better to set it in ath11k.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
