Subject: [PATCH] inspect: fix inspection of partition-less devices
 (RHBZ#1661038)

When parsing "xdev"-kind devices, do not assume that the partition
number can be converted to integer: re_xdev accepts an empty part of the
partition number, so just handle as it is, as string.

This fixes a regression due to the conversion of the inspection code to
OCaml, as the old C version did not have this issue.

(cherry picked from commit cf6b527824b2a8dc6e8bc65e38ebdceb227e6db1)
