BUG/MINOR: mux-h1: Capture ignored parsing errors

When the option "accept-invalid-http-request" is enabled, some parsing errors
are ignored. But the position of the error is reported. In legacy HTTP mode,
such errors were captured. So, we now do the same in the H1 multiplexer.

If required, this patch may be backported to 2.0 and 1.9.
