Subject: fix rescan_partitions to return errors properly
From: suzuki <suzuki@xxxxxxxxxx>
The only error code which comes from the partition checkers is -1, when they
finds an EIO. As per the discussion, ENOMEM values were ignored, as they
might scare the users.
So, with the current code, we end up returning -1 and not EIO for the ioctl()
calls. Which doesn't give any clue to the user of what went wrong.
