Andrew Lytvynov 29e98e18f8 ssh/tailssh: use a local error instead of gossh.ErrDenied (#10743) ... ErrDenied was added in [our fork of x/crypto/ssh](acc6f8fe8d) to short-circuit auth attempts once one fails. In the case of our callbacks, this error is returned when SSH policy check determines that a connection should not be allowed. Both `NoClientAuthCallback` and `PublicKeyHandler` check the policy and will fail anyway. The `fakePasswordHandler` returns true only if `NoClientAuthCallback` succeeds the policy check, so it checks it indirectly too. The difference here is that a client might attempt all 2-3 auth methods instead of just `none` but will fail to authenticate regardless.
