From: Emil Velikov <emil.velikov at collabora.com>

... to get the user_data. Like everywhere else through weston.

Some ancient patch, that I had locally.

It should be fine to land as-is, although it brings an interesting
question - should one keep struct linux_dmabuf_buffer private or not?

- No - the get/set user data accessors seem (sort of) pointless
- Yes - one would need extra accessor for ::attributes, ...(?)
