qcacmn: Ignore default country update during wlan restart

Browse Source 
After driver load and interface up, if user changes the country code
and performs the interface down, now if interface change timer expires,
stop modules is invoked. When user again tries to do interface up, as a
part of start modules, update channel list indication comes from FW
with default country info from BDF file which overwrites user specified
country information.

To resolve this issue, if current country is set by user and if
driver gets notification to update channel list from FW with
different country code during restart of wlan modules then ignore
master channel list and send the current user country to FW.
