BUG/MEDIUM: conn-stream: Only keep app layer flags of the endpoint on reset

The commit a6c4a4834 ("BUG/MEDIUM: conn-stream: Don't erase endpoint flags
on reset") was too laxy on reset. Only app layer flags must be preserved. On
reset, the endpoint is detached. Thus all flags set by the endpoint itself
or concerning its type must be removed.

Without this fix, we can experienced crashes when a stream is released while
a server connection attempt failed. Indeed, in this case, endpoint of the
backend conn-stream is reset. But the endpoint type is still set. Thus when
the stream is released, the endpoint is detached again.

This patch is 2.6-specific. No backport needed. This commit depends on the
previous one ("MINOR: conn-stream: Add mask from flags set by endpoint or
app layer").
