By default keep mutex locked if we tried to write #374

The wolfSSL TLS engine requires an SSL_Write that returns WANT_WRITE to be called with the same buffer/sz, not a different one, even if no data was sent. If user wants to enable the feature anyways they can use WOLFMQTT_ALLOW_NODATA_UNLOCK. Only the write has this logic as the issue doesn't exist for an SSL_Read.
