[PATCH 1/1] kpartx: Use absolute paths to create mappings

[Stef Walter <stefw@redhat.com>]

kpartx -d now uses absolute paths to delete mappings, since the
commit 9bdfa3eb8e24b668e6c2bb882cddb0ccfe23ed5b. We should use
those same absolute paths to create the mappings.

Without this patch, the following workflow (as seen in the
manual page for kpartx) fails to actually remove the devices:

    # kpartx -av disk.img
    ...
    # kpartx -d disk.img
