BUG/MINOR: http-ana: Don't increment HTTP error counter on read error/timeout

This should have been fixed when the commit "BUG/MINOR: http-ana: Don't
increment HTTP error counter on internal errors" was backported but I forgot
to do so. The HTTP error counter must not be incremented if a read error or
a read timeout is encountered. Parsing error are already reported by the
mux.

This patch must be backported as far as 2.0, on the HTX part only.
