media: imx-jpeg: Prevent decoding NV12M jpegs into single-planar buffers

If the application queues an NV12M jpeg as output buffer, but then
queues a single planar capture buffer, the kernel will crash with
"Unable to handle kernel NULL pointer dereference" in mxc_jpeg_addrs,
prevent this by finishing the job with error.
