qcacld-3.0: Fix failed to roam to 320 MHz AP issue

Browse Source 
When create vdev, CC is US, max_allowed_bw was 160 MHz, so host set EHT
cap without 320 MHz supported to F/W.
Then APPs reset CC to Japan, max_allowed_bw became 320 MHz, but host
didn’t update eht cap with 320 MHz to F/W correctly especially when
STA disconnected. So F/W can’t roamed to AP with 320 MHz BW.

To fix it, if max_allowed_bw become 320 MHz after CC changed, update eht
cap with 320 MHz supported to F/W correctly, if sta disconnected, update
CAP IE too.
