client: No longer fail connection if sideband was not announced.

Sideband has become mandatory in paraslash-0.5.0, and the current
para_client does not work with older server versions anyway. Hence
this change has no impact on compatibility.

The E_INCOMPAT_FEAT error code is now unused and can be removed.
