media: Quit parsing stream if doesn't start with SOI

Browse source

In the case we get an invalid stream, such as from v4l2-compliance
streaming test, jpeg_next_marker will end up parsing the entire
stream. The standard describes the high level syntax of a jpeg
as starting with SOI, ending with EOI, so return error if the very
first 2 bytes are not SOI.
