[PATCH 13/15] mount.nfs: mountproto does not support RDMA

[Chuck Lever <chuck.lever@oracle.com>]

Clean up.  Our client does not support the MNT protocol on RDMA.

nfs_mount_protocol() isn't invoked for RDMA mounts (they are shunted
off before nfs_options2pmap() is invoked).  But in case it ever is,
it should return the expected response.
