netfilter: nf_tables: fix oob access
[ Upstream commit 3e38df136e453aa69eb4472108ebce2fb00b1ba6 ]
BUG: KASAN: slab-out-of-bounds in nf_tables_rule_destroy+0xf1/0x130 at addr ffff88006a4c35c8
Read of size 8 by task nft/1607
When we've destroyed last valid expr, nft_expr_next() returns an invalid expr.
We must not dereference it unless it passes != nft_expr_last() check.
