For hdr parse error, it can return false without any assignments
which cause following build warning.

drivers/media/platform/s5p-jpeg/jpeg-core.c: In function 's5p_jpeg_parse_hdr':

drivers/media/platform/s5p-jpeg/jpeg-core.c:433: warning: 'height' may be used uninitialized in this function
drivers/media/platform/s5p-jpeg/jpeg-core.c:433: warning: 'width' may be used uninitialized in this function
