There is no need to use DRM dumb pool if buffer to render is already a DMABuf, just import it and render it. This fixes a DMAbuf memory leakage when waylandsink downstream element exports DMABuf while waylandsink is configured to be DMABuf exporter (drm-device=/drv/dri/card0): gst-launch-1.0 v4l2src io-mode=4 ! gtkwaylandsink drm-device=/dev/dri/card0 leakage identfied with command: watch "cat /sys/kernel/debug/dma_buf/bufinfo | grep attached " Fixes #2729 Part-of: <https://gitlab.freedesktop.org/gstreamer/gstreamer/-/merge_requests/5350>
