BUG/MEDIUM: mux-h2: make sure to always report HTX EOM when consumed by headers

The way htx_xfer_blks() was used is wrong, if we receive data, we must
report everything we found, not just the headers blocks. This ways causing
the EOM to be postponed and some fast responses (or errors) to be incorrectly
delayed.

No backport is needed.
