mask prepare_resize inline attribute with inline-more feature

fix #315

I don't think prepare_resize is the issue here since it is only called from one place (resize_inner). Perhaps the #[inline(always)] should be removed from resize_inner instead?

Yes, I think so, resize_inner is the better place to do the modify. Thx.
