BUG/MEDIUM: filters: Fix a typo when a filter is attached blocking the release

When a filter is attached to a stream, the wrong FLT_END analyzer is added
on the request channel. AN_REQ_FLT_END must be added instead of
AN_RES_FLT_END. Because of this bug, the stream may hang on the filter
release stage.

It seems to be ok for HTTP filters (cache & compression) in HTTP mode. But
when enabled on a TCP proxy, the stream is blocked until the client or the
server timeout expire because data forwarding is blocked. The stream is then
prematurely aborted.

This bug was introduced by commit 26eb5ea35 ("BUG/MINOR: filters: Always set
FLT_END analyser when CF_FLT_ANALYZE flag is set"). The patch must be
backported in all stable versions.
