BUG/MINOR: h1-htx: Don't forget to init flags in h1_format_htx_msg function

The regression was introduced by commit 187ae28 ("MINOR: h1-htx: Add
function to format an HTX message in its H1 representation"). We must be
sure the flags variable must be initialized in h1_format_htx_msg() function.

This patch must be backported with the commit above.
