msm: kgsl: Detect and avoid malformed ioctl codes Because we were using _IO_NR, one could construct a malformed ioctl code that would avoid allocating memory yet go to a function that expected that memory. Still use _IO_NR to index the array of ioctls, but check that the full values match before jumping to the helper function.
