ssh: avoid quadratic complexity from long banner

Ticket: 6799

When we find an overlong banner, we get into the state just
waiting for end of line, and we just want to skip the bytes
until then.
Returning AppLayerResult::incomplete made TCP engine retain
the bytes and grow the buffer that we parsed again and again...
