[ Upstream commit 4f5bb7ff8b8d4bafd91243fc969ed240e67aa1ca ]
8822C is a 2x2 11ac chip, and then NSS must be less or equal to 2. However, current nss of hw cap is 3, likes hw cap: hci=0x0f, bw=0x07, ptcl=0x03, ant_num=7, nss=3
This commit adds constraint to make sure NSS <= rf_path_num, and result looks like hw cap: hci=0x0f, bw=0x07, ptcl=0x03, ant_num=7, nss=2
