nfs/blocklayout: support RH/Fedora dm-mpath device nodes

Instead of reusing the wwn-* names for multipath devices nodes RHEL and
Fedora introduce new dm-mpath-uuid-* nodes with a slightly different
naming scheme.  Try these names first to ensure we always get a
multipath-capable device if it exists.
