Sachin Ahuja 19cae30b59 qcacld-3.0: Don't set adapter dev to NULL in hostapd unint 
With the existing design the panic is seen with the below
scenario.
1) As a part of country change, driver takes the dev_hold and proceed
   with the adapter access.
2) In another thread, del virtual iface is called which calls the
   unregister netdev. This kernel API(unregister netdev) calls the
   hdd_hostapd_unint where the adapter->dev is set to NULL. After
   this  unregister_netdev waits for the dev_put as driver has
   taken the dev_hold in 1). Till this dev_put happens
   unregister_netdev will wait.
3) Once the adapter access is completed as a part of 1), driver
   does the dev_put with the pointer dev which is made as NULL in 2).

To avoid this crash, don't set the adapter->dev to NULL in
hostapd unint.
