Eduard Shishkin 3db20bccef zipl_helper.device-mapper: Add missed step in logical device resolution

Steps to reproduce the problem:

\# lsblk

NAME                             MAJ:MIN RM  SIZE RO TYPE  MOUNTPOINT
loop0                              7:0    0    5G  0 loop
|-loop0p1                        253:15   0  128M  0 part
`-loop0p2                        253:16   0  4.9G  0 part  /mnt

\# ./zipl_helper.device-mapper 253:16

Expected result:

targetbase=7:0
targettype=SCSI
targetblocksize=4096
targetoffset=32784

Actual result:

targetbase=253:16
targettype=SCSI
targetblocksize=4096
targetoffset=32784

The problem is in a missed step which resolves the uppermost
logical dm-device to a physical device. Reproducible only for loop
devices.

Add missing step to correctly resolve to a physical device.
