[media] v4l2-ioctl.c: handle PREPARE_BUF like QUERYBUF
The core code for PREPARE_BUF didn't take the multiplanar case into account, which might cause page faults. Handle PREPARE_BUF just like QUERYBUF and QBUF/DQBUF. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
