In 11D scan procedure if WMI_11D_NEW_COUNTRY_EVENTID event is
received, host processes 11d new country code event.
Host driver as a response sends WMI_SCAN_CHAN_LIST_CMDID
new channel list cmd to firmware.
As a result the ongoing scan procedure is aborted by firmware,
and if the scan was a first scan for connection, then it would
lead to connection latency as the supplicant then have to
scan again.
Fix is to check if any scan is in progress, then delay
WMI_SCAN_CHAN_LIST_CMDID channel list command to FW till
the current scan is complete.
