There is no reason to split those two operations so combining
two functions - egl_dmabuf_create_sync and egl_dmabuf_create_fence.

Can you send this change as a different patch series, or earlier in the
series?
You should also remove qemu_dmabuf_{set,get}_sync() and associated fields

It should probably return qemu_dmabuf_get_fence_fd() instead. The function
should be renamed with _fd postfix since you make it return the fd.
