As kmalloc can return NULL pointer, it should be better to
check the return value and return error, same as
coda_jpeg_decode_header.

coda9_jpeg_dec_huff_setup() never returns anything but 0. Drop
return value and superfluous error handling at the call site.

If JPEG header parsing fails, output a single message instead of two
messages that say the same thing.

If decoding fails because the output buffer does not contain a
valid header, set the error flag on the returned capture buffer.

The JPEG decoder in the CODA960 VPU can downscale images while decoding,
with a factor of 1/2, 1/4, or 1/8.

If the decoder prepare_run callback returns an error, the hardware
is never started and v4l2_m2m_job_finish() is called immediately,
currently in every error path.
Remove the duplicated job_finish calls from the error paths and reuse
the v4l2_m2m_job_finish() at the end of coda_pic_run_work instead.

As the end goal is to have platform drivers split by vendor,
rename coda/ to chips-media/.
