[PATCH 3.18 056/144] NFS: Ignore transport protocol when detecting server trunking




3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

[ Upstream commit 7a01edf0058df98d6cc734c5a4ecc51f929a86ec ]

Detect server trunking across transport protocols. Otherwise, an
RDMA mount and a TCP mount of the same server will end up with
separate nfs_clients using the same clientid4.
