EDD fix
This patch fixes EDD support where the BIOS reports a length lower than the
actual length of raw_data in sysfs. That's no problem -- the check only
needs to catch the case where the sysfs file is *smaller* than the
BIOS reported length.
Also add a newline at the end of the error message.
The problem was introduced in 3bf0213789d56054f601c5a06372f78567aacdd9 by
myself, the initial EDD implementation.
