[media] coda: relax coda_jpeg_check_buffer for trailing bytes

Browse source

coda_jpeg_check_buffer only cares about the buffer length and contents,
so change the parameter type back from v4l2_vb2_buffer to just the
vb2_buffer.
Instead of just checking the first and last bytes for the SOI and EOI
markers, relax the EOI marker check a bit and allow up to 32 trailing
bytes after the EOI marker as hardware generated JPEGs sometimes contain
some alignment overhead.
