    NFS/SUNRPC: don't lookup machine credential until rpcauth_bindcred(). · 5e16923b

    When NFS creates a machine credential, it is a "generic" credential,
    not tied to any auth protocol, and is really just a container for
    the princpal name.
    This doesn't get linked to a genuine credential until rpcauth_bindcred()
    is called.
    The lookup always succeeds, so various places that test if the machine
    credential is NULL, are pointless.
    As a step towards getting rid of generic credentials, this patch gets
    rid of generic machine credentials.  The nfs_client and rpc_client
    just hold a pointer to a constant principal name.
    When a machine credential is wanted, a special static 'struct rpc_cred'
    pointer is used. rpcauth_bindcred() recognizes this, finds the
    principal from the client, and binds the correct credential.
