Thierry FOURNIER ef6a2115fd BUG/MEDIUM: lua: fix infinite loop about channel
Before this patch, each yield in a Lua action set a flags to be
waked up when some activity were detected on the response channel.
This behavior causes loop in the analyzer process.

This patch set the wake up on response buffer activity only if we
really want to be waked up on this activity.
