commit 64f6a5d192 ("container_of: add container_of_const()
that preserves const-ness of the pointer") is nice. Let's use
it so that we don't accidentally cast away the const from our
state pointers.
The only thing I don't particularly like about container_of_const()
is that it still accepts void* in addition to the proper pointer
types, but that's how most other things in C work anyway so I
guess we can live with it.
And while at it rename the macro arguments to be a bit more
descriptive than just 'x'.
TODO: maybe convert *all* container_of() uses to container_of_const()?
