qcacmn: Fix target assert caused due to DBS band limitation WAR

Browse Source 
In some boards, FW can send preferred HW mode as DBS and num HW modes as 2.
In this scenario, with I65ab1b803f652cf6b636cd885c6c0afd2251b0ce change we
observed a target  assert.

To fix the assert, apply the DBS mode phy0 band limitation WAR only if FW
sends preferred mode as DBS and DBS_SBS.
