[libvirt] [PATCH 3/5] storage: Check FS pool source during virStorageBackendFileSystemIsMounted
https://bugzilla.redhat.com/show_bug.cgi?id=1025230
When determining whether a FS pool is mounted, rather than assuming that
the FS pool is mounted just because the target.path is in the mount list,
let's make sure that the FS pool source matches what is mounted
