staging/cxt1e1/linux.c: Correct arbitrary memory write in c4_ioctl()
The function c4_ioctl() writes data from user in ifr->ifr_data
to the kernel struct data arg, without any iolen bounds checking.
This can lead to a arbitrary write outside of the struct data arg.
Corrected by adding bounds-checking of iolen before the copy_from_user().
