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.

I had the same problem with a completely different architecture and device,
and this patch fixed it.
