Title: pool: reorder ip addresses returned to NFS client

according to NFS spec pool client can select a best matching IP
address from the list available IP addresses of the pool.

Nevertheless, current client implementation in RHEL-6 takes first
one from the list and, some times, makes a wrong choice for mutihomed
pools.

This change will put 'expected correct' interface as a first element
of the returned list.
