Oran Agra fb0783c710 Handle output buffer limits for Module blocked clients (#8141)
Module blocked clients cache the response in a temporary client,
the reply list in this client would be affected by the recent fix
in #7202, but when the reply is later copied into the real client,
it would have bypassed all the checks for output buffer limit, which
would have resulted in both: responding with a partial response to
the client, and also not disconnecting it at all.

(cherry picked from commit 11e0c4739b40c23a70aff5287e67e8ef6418bb2a)
