memfd: simplify API

Now, that the memfd stuff is not exported anymore, we can simplify a few
things:

Use assert() instead of assert_return(), since this is used internally
only, and we should be less permissive then.

No need to pass an allocated fd back by call-by-reference, we can just
directly return it.
