Subject: libparted: Canonicalize /dev/md/ paths
References: bsc#1078820
Patch-mainline: submitted, 2018-02-20

The BLKPG* ioctl handling relies on getting the current partitions
from /sys/block/$devname/. With an md name like e.g. "vol0", the
block device to be used cannot be found and the BLKPG* ioctls are
used for all partitions. So canonicalize /dev/md/ paths as well.

Test: t6100-mdraid-partitions
