[patch] do not try to remove stale directories in .hal-mtab on unmount

[Martin Pitt]

Hi all,

in [1], some users had some trouble with unmounting devices:

 Cannot unmount the volume.

 Details:
 Cannot remove directory

this is due to stale entries in .hal-mtab.

A patch [2] was proposed to robustify the matching in .hal-mtab to
pick the right directory when libhal_volume_get_mount_point() succeeds
(if not, it doesn't change behaviour).

IMHO the patch should use a new variable for the
libhal_volume_get_mount_point() result, otherwise it pointlessly does
a strcmp() in every loop iteration.

The idea looks fine to me IMHO. As further mitigation, .hal-mtab
should be removed on boot, but that's something for the distros of
course.

If you like it, I'll clean it up and submit a patch against git head.

Thanks,

Martin
