nfs41: exchange_id operation
Implement the exchange_id operation conforming to http://tools.ietf.org/html/draft-ietf-nfsv4-minorversion1-26 Unlike NFSv4.0, NFSv4.1 requires machine credentials. RPC_AUTH_GSS machine credentials will be passed into the kernel at mount time to be available for the exchange_id operation. RPC_AUTH_UNIX root mounts can use the UNIX root credential. Store the root credential in the nfs_client struct. Without a credential, NFSv4.1 state renewal fails.
