qcacmn: Disallow moving to single MAC mode when a 2.4GHz connection exist

Browse source 
After the P2P GO is up on 2.4 GHZ, the opportunistic upgrade
timer handler is sending request to move to single MAC mode.
Since 2.4 GHZ connection is always on MAC1 in DBS 2X2 capable
HW, this is causing P2P connection failure. Add fix to not
downgrade to single MAC mode when there exist a 2.4 GHZ
connection.
