Re: [PATCH 6.1.y] netfilter: nf_tables: make nft_object rhltable per table

The nft_object rhltable is global, this allows for accessing objects
that are being dismangled from lookup path by other existing netns.
Given the nft_obj_destroy() releases the object inmediately, this might
lead to use-after-free of these objects that are being released.
Make the existing rhltable per table to address this issue to deal with

Queued for 6.1, thanks.
