BUG/MINOR: tcp-rules: Preserve the right filter analyser on content eval abort

When a tcp-request or a tcp-response content ruleset evaluation is aborted, the
corresponding FLT_END analyser must be preserved, if any. But because of a typo
error, on the tcp-response content ruleset evaluation, we try to preserve the
request analyser instead of the response one.

This patch must be backported to 2.2.
