Subject: [PATCH 7/9] egl-wayland: fix device name case where only wl_drm
 exists

This fixes a problem in commit 6355c16 where we do not properly wait
for a roundtrip to get the wl_drm name, which can lead to failing to
initialize and falling back to another ICD. This fix also properly
prioritizes the device provided by dmabuf feedback over the wl_drm
name, only using wl_drm if dmabuf did not provide anything.
