Subject: PipeWire: stop log spam from RequestProcess events

Fixes an issue where PipeWire error logs are continuously created whenever there is audio
 playing or if the "keep audio device alive" setting is enabled.

This issue has appeared ever since PipeWire v1.2.4 introduced a change that forwards RequestProcess events.
Thus it affects Kodi 21.2 on Trixie testing.
Pipewire v1.2.4 change: https://gitlab.freedesktop.org/pipewire/pipewire/-/commit/c6ae68b9326f235aa6ee11b62b8e6a9126bb2e22

Origin: upstream, https://github.com/xbmc/xbmc/pull/26441
Bug: https://github.com/xbmc/xbmc/issues/26122
