BUG/MEDIUM: http/htx: Fix handling of the option abortonclose

Because the flag CF_SHUTR is no more set to mark the end of the message by the
H2 multiplexer, we can rely on it again to detect aborts. there is no more need
to make a check on the flag SI_FL_CLEAN_ABRT when the option abortonclose is
enabled. So, this option should work as before for h2 clients.

This patch must be backported to 1.9 with the previous EOI patches.
