qcacld-3.0: Don't change self cap when change BW during connected

When set max channel width to less than 320 MHz during connected,
eht_cap.support_320mhz_6ghz is disabled, then even roamed to new 320 MHz
AP, channel width can't be 320 MHz.

To fix it, when change max channel width during connected, just update
channel width and send OMI to AP, update vdev bss chan BW and peer
phymode, don’t change self cap including ht/vht/he/eht cap and channel
bonding mode, then don't affect roaming, CSA case and reconnection cases.
