Anirban Chakraborty 0866d96da0 qlcnic: Fix driver load issue in FW hang 
If there is a FW hang when the driver loads, it can not determine the FW operational
mode. Fix it by checking the FW state first before issuing any FW commands to
determine its capabilities and thereby detecting driver operational mode.
