Avoid possible race on NFS shares in which may that the network devices disappears
before the associated NFS share becomes unmounted (bug #861489).
To do this make sure that sys-subsystem-net-devices-<iface>.device used for the
NFS share is added as "After=" dependency to the <nfs-share-mount-point>.mount.
