msm: camera: Do not pass kptr in copy_from_user
Do not call copy_from_user in ioctl handler if CONFIG_COMPAT
is defined.
In 64 bit kernel and 32 bit userspace, ioctl call invokes
compat_ioctl. First copy_from_user is done in compat_ioctl then
pointer is passed to unlocked_ioctl for actual processing. In
unlocked_ioctl again copy_from_user is called on kernel pointer.
