I'm not sure why we have a copy of include/linux/hashtable.h in
scripts/, but it's silly that it has diverged slightly from what we do
in-kernel, and now we're chasing bugs caused by that divergence.

Can we instead align both back to be the same, or even use
include/linux/hashtable.h directly from scripts/?
