compat: Fix module_init return type from void to int.

086f3a1 overrode module_init to make it depend on compat, but the
overriding module_init has return type 'void', so strange things would
happen when the module loading code see that init_module() returns
positive values.  This patch makes it return the value returned by
the overriden module_init.
