[Impact]
On Dell platform with Microdia Integrated webcam, the Cheese preview is stuck on jammy.

[Test Plan]
1. Install Jammy on Dell platform with Microdia Integrated webcam
2. Install the updated pipewire packages by $ sudo apt dist-upgrade
3. Open Cheese
3. The preview works normally

[Where problems could occur]
The patches tries to dequeue the shared buffer, instead of pool buffer to prevent the pool buffer being corrupted.
It is in upstream from 0.3.52 to 0.3.56, and there is no regression found,
so the risk is low.
