BUG/MINOR: filters: Set right FLT_END analyser depending on channel

A bug was introduced by the commit 26eb5ea35 ("BUG/MINOR: filters: Always
set FLT_END analyser when CF_FLT_ANALYZE flag is set"). Depending on the
channel evaluated, the rigth FLT_END analyser must be set. AN_REQ_FLT_END
for the request channel and AN_RES_FLT_END for the response one.

Ths patch must be backported everywhere the above commit was backported.
