Subject: Bug 1953080 - WebRTC backport: Fix build with Pipewire 1.4
 r=pehrsons,webrtc-reviewers

Pipewire 1.4 changed some functions from taking void*
to taking the actual type they expect, which makes
some code that built with 1.2 no longer build with 1.4.

For older versions, this is effectively a no-op.

This is a simple backport of an WebRTC upstream change.
