wifi: rtw89: declare EXT NSS BW of VHT capability 



According to IEEE Std. 802.11, it defines:
Indicates whether the STA is capable of interpreting the Extended NSS BW
Support subfield of the VHT Capabilities Information field.

Some AP such as TP-LINK BE19000 would check it for bandwidth settings, so
causes 80MHz rate when associating on 160 MHz bandwidth. Declare this
capability to yield expected result.
