MINOR: htx: unconditionally handle parsing errors in requests or responses

The htx request and response processing functions currently only check
for HTX_FL_PARSING_ERROR on incomplete messages because that's how mux_h1
delivers these. However with H2 we have to detect some parsing errors in
the format of certain pseudo-headers (e.g. :path), so we do have a complete
message but we want to report an error.

Let's move the parse error check earlier so that it always triggers when
the flag is present. It was also moved for htx_wait_for_request_body()
since we definitely want to be able to abort processing such an invalid
request even if it appears complete, but it was not changed in the forward
functions so as not to truncate contents before the position of the first
error.
