Host receives QCA_WLAN_VENDOR_ATTR_CONFIG_CHANNEL_WIDTH vendor
command indication to update STA adapter channel width.
On receiving channel width update indication from upper layer,
first host updates internally and send new channel width value
to FW via WMI_VDEV_PARAM_CHWIDTH_WITH_NOTIFY.
Target firmware should take care of notifying associated peers
(except TDLS) about change in bandwidth, through OMN/OMI
notification before performing bandwidth update internally.
