wlan:Check priviledge permission for SET_CHANNEL_RANGE

prima to qcacld-2.0 propagation.

Kernel assumes all SET IOCTL commands are assigned with even
numbers. But in our WLAN driver, some SET IOCTLS are assigned with
odd numbers. This leads kernel fail to check, for some SET IOCTLs,
whether user has the right permission to do SET operation.
Hence, in driver, before processing SET_CHANNEL_RANGE IOCTL,
making sure user task has right permission to process the command.
