I think it is OKish to do this in a define like this, but...

...I think this is misleading. It's definitely not const, so switching to
container_of_const suggests that there is some 'constness' involved, which
isn't the case. I'd leave this just as 'container_of'. This also reduces the
size of the patch, since this is done in quite a few places.
