netfilter: nft_rbtree: fix data handling of end interval elements ...
This patch fixes several things which related to the handling of
end interval elements:
* Chain use underflow with intervals and map: If you add a rule
using intervals+map that introduces a loop, the error path of the
rbtree set decrements the chain refcount for each side of the
interval, leading to a chain use counter underflow.
* Don't copy the data part of the end interval element since, this
area is uninitialized and this confuses the loop detection code.
* Don't allocate room for the data part of end interval elements
since this is unused.
So, after this patch the idea is that end interval elements don't
have a data part.
