qcacld-3.0: Update cktn BW from bcn if bss peer BW is incorrect

If session BW is 160 MHz or higher and peer BW is reduced below
160 MHz in assoc response, STA resets HE 160 MHz MCS rates to
0xffff that results in FW assert. To avoid STA crash, add a
check to get reduced peer BW from beacon instead of allowing
160 MHz association.
