netfilter: nft_bitwise: fix register tracking
At the end of `nft_bitwise_reduce`, there is a loop which is intended to
update the bitwise expression associated with each tracked destination
register. However, currently, it just updates the first register
repeatedly. Fix it.
Fixes: 34cc9e52884a ("netfilter: nf_tables: cancel tracking for clobbered destination registers")
