Update TLSSession::checkDirection() doc 

Make it clear that TLS_WANT_READ must be returned if underlying
SSL/TLS lib does not indicate I/O direction. This is because
SocketCore sets wantRead_ = true when TLS_WANT_READ is returned and
otherwise sets wantWrite_ = true. We only want to set wantWrite_ =
true iff we have some pending data to send.
