	Jan Patera <patera@pictview.com> spotted a problem with my last fix
	for #1774591:

	* libexif/exif-content.c: (exif_content_remove_entry) Recover
	correctly in case of error by remembering the original size of the
	realloc'ed data.
	* libexif/exif-data.c: (exif_data_save_data_entry),
	(exif_data_save_data_content) Same here.
	* libexif/canon/exif-mnote-data-canon.c:
	(exif_mnote_data_canon_save), (exif_mnote_data_canon_load) Same here.
        * libexif/fuji/exif-mnote-data-fuji.c:
        (exif_mnote_data_fuji_save), (exif_mnote_data_fuji_load) Same here.
        * libexif/olympus/exif-mnote-data-olympus.c:
        (exif_mnote_data_olympus_save) Same here.
