BUG/MEDIUM: dns: Don't yield in do-resolve action on a final evaluation

When an action is evaluated, flags are passed to know if it is the first call
(ACT_OPT_FIRST) and if it must be the last one (ACT_OPT_FINAL). For the
do-resolve DNS action, the ACT_OPT_FINAL flag must be handled because the
action may yield. It must never yield when this flag is set. Otherwise, it may
lead to a wakeup loop of the stream because the inspected-delay of a tcp-request
content ruleset was reached without stopping the rules evaluation.

This patch is related to the issue #222. It must be backported as far as 2.0.
