Fix potential infinite loop in jpeg error handling code.

Turns out that jpeg_finish_decompress can throw errors, hence
can cause an infinite loop. This is fixed here by changing the
jpeg error code to be fz_throw based.

Thanks to zeniko for this patch.

This highlights something that I hadn't fully appreciated before;
anything that throws in a fz_always region will reenter that region.
I think I have a way to fix this so that any throws in the
fz_always region go immediately to the fz_catch.
