NFS: Add nfs_client behavior flags
"noresvport" and "discrtry" can be passed to nfs_create_rpc_client() by setting flags in the passed-in nfs_client. This change makes it easy to add new flags. Note that these settings are now "sticky" over the lifetime of a struct nfs_client, and may even be copied when an nfs_client is cloned.
