FPII-1851:Elevation of Privilege Vulnerability in Qualcomm Wi-Fi driver (Device Specific) CVE-2015-0571 ANDROID-26763920

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_VAR_INTS_GETNONE, making
sure user task has right permission to process the command.
