Subject: [PATCH 027/359] Manage: fix removal of non-existent devices.
References: bsc#1081910

"--remove detached" and others stopped working a while
back when I refactored some code.
For 'remove' and  'fail', the device may not exist so
if it is  "MM:mm", (e.g. added by "detached"), just parse
out the numbers.
