Revert "lib: Ensure we don't find bind mounts for device target"

Browse Source 
Resolves: https://issues.redhat.com/browse/RHEL-56832
Upstream Status: RHEL-only

This reverts commit 099aead590.

Currently get_mntpoint_from_target incorrectly return empty result for
targets that contain square bracket '[', e.g
 - eng.redhat.com:/srv/[nfs]
 - [2620:52:0:a1:217:38ff:fe01:131]:/srv/[nfs]
 - /dev/mapper/rhel[disk]

get_mntpoint_from_target is also used in several places. To avoid
RHEL-56832 and other possible regressions, revert the bad commit.
