BUG/MINOR: tcpcheck: Don't forget to reset tcp-check flags on new kind of check

When a new kind of check is found during the parsing of a proxy section (via
an option directive), we must reset tcpcheck flags for this proxy. It is
mandatory to not inherit some flags from a previously declared check (for
instance in the default section).

This patch must be backported as far as 2.2.
