Subject: [PATCH] mpath: Update path in CheckPool function

https://bugzilla.redhat.com/show_bug.cgi?id=1230664

Per the devmapper docs, use "/dev/mapper" or "/dev/dm-n" in order to
determine if a device is under control of DM Multipath.

So add "/dev/mapper" to the virFileExists, leaving the "/dev/mpath"
as a "legacy" option since it appears for a while it was the preferred
mechanism, but is no longer maintained
