Subject: CLEANUP: checks: remove minor warnings for assigned but not used variables
X-Git-Tag: v1.5-dev13~197
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=392e9390e63316b30865ccfc5c961c1a0a9f0c2f;p=thirdparty%2Fhaproxy.git

CLEANUP: checks: remove minor warnings for assigned but not used variables

We don't use the return value from snd_buf/rcv_buf anymore since we only
rely on the connection flags.
