FPII-1872:CR:930935-Improper access control on WLAN_PRIV_SET_CHAR_GET_NONE (SIOCIWFIRSTPRIV + 3)
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_CHAR_GET_NONE IOCTLs, making
sure user task has right permission to process the command.
