[PATCH -stable,5.10 0/2] Netfilter stable fixes for 5.10

Hi Greg, Sasha,

The following small batch contains two more fixes for a WARNING splat on chain unregistration and UaF in the flowtable unregistration that is exercised from netns path for 5.10 -stable.

I am using original commit IDs for reference:

1) 6069da443bf6 ("netfilter: nf_tables: unregister flowtable hooks on netns exit")

2) f9a43007d3f7 ("netfilter: nf_tables: double hook unregistration in netns path")

Please, apply.

Thanks.
