In rxe_pool.c currently there are many cases where it is necessary to
compute the offset from a pool element struct to the object containing
the pool element in a type independent way. By saving a pointer to the
object when they are created extra work can be saved.

This would be better to just add a static_assert or build_bug_on that
the offsetof() the rxe_pool_entry == 0. There is no reason for these
to be sprinkled at every offset

Then you don't need to do anything at all
