BUG/MINOR: tcpcheck: Disable QUICKACK for default tcp-check (with no rule)

The commit 871dd8211 ("BUG/MINOR: tcpcheck: Disable QUICKACK only if data
should be sent after connect") introduced a regression. It removes the test
on the next rule to be able to disable TCP_QUICKACK when only a connect is
performed (so no next rule).

This patch must be backported as far as 2.2.
