Olaf Hering d55ae1cc8f hotplug: fix busy loop device detection ...

Improve busy loop device detection after changeset 22773:02c0af2bf280

The intention is not to find the file to be mounted in the losetup -a
output.  What matters are existing mounted files with the same dev:inode
as the new file.  So the fix is to apply variable expansion which
happens only without double quotes.  Otherwise $dev will contain
newlines for hardlinked files, as mentioned in the commit message from
the changeset above.

losetup -a does also truncate long filenames to 62 chars due to ioctl
limitations.  This part is fixed with 2.6.37 where the filename can be
obtained from sysfs. As a result very long filenames will be missed.
