BUG/MEDIUM: htx: Adjust length to add DATA block in an empty HTX buffer

htx_add_data() is able to partially consume data. However there is a bug
when the HTX buffer is empty.  The data length is not properly
adjusted. Thus, if it exceeds the HTX buffer size, no block is added. To fix
the issue, the length is now adjusted first.

This patch must be backported as far as 2.0.
