This is all completely academic, since module_init() is a declaration
that won't be inside any code, but in general it's better still to use
the do { } while (0) idiom like

#define module_init(x) do { __initcall(x); __module_init_disable(x); } while (0)

so it won't break code like

if (..)
module_init(x);
else
something_else();

(Yes, that code is nonsense but if you're going to nitpick, go all the way...)
