fix memory leaks in pdf_load_jpx and fz_new_image_from_pixmap

fz_new_image_from_pixmap expects that the pixmap's colorspace has two
references which is contrary to expectations. If it instead addrefs the
pixmap's colorspace, the only caller pdf_load_jpx can consistently
drop the colorspace after passing it to fz_load_jpx.

Also, if the contract is that whatever is passed into
fz_new_image_from_pixmap belongs to the new image, then the pixmap also
has to be dropped on error so that it isn't leaked.
