[libvirt] [PATCH 1/3] 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mechanism, but is no longer maintained
