NFS: Expand server address storage in nfs_client struct
Prepare for managing larger addresses in the NFS client by widening the nfs_client struct's cl_addr field. Signed-off-by: Chuck Lever <chuck.lever@oracle.com> Cc: Aurelien Charbon <aurelien.charbon@ext.bull.net> (Modified to work with the new parameters for nfs_alloc_client) Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
