For the architectures with it's own module_alloc(), if module init size is zero, avoiding module_alloc_update_bounds() and memset() no-op calls also eliminates warn_alloc_failed() zero-size warning in __vmalloc_node_range().

Please fix __vmalloc_node_range() instead to return ZERO_SIZE_PTR. And of course, vfree() to use ZERO_OR_NULL_PTR().

Thanks, Rusty.
