Taehee Yoo 97a0549b15 netfilter: nft_meta: fix wrong value dereference in nft_meta_set_eval 
In the nft_meta_set_eval, nftrace value is dereferenced as u32 from sreg.
But correct type is u8. so that sometimes incorrect value is dereferenced.

Steps to reproduce:

   %nft add table ip filter
   %nft add chain ip filter input { type filter hook input priority 4\; }
   %nft add rule ip filter input nftrace set 0
   %nft monitor

Sometimes, we can see trace messages.

   trace id 16767227 ip filter input packet: iif "enp2s0"
   ether saddr xx:xx:xx:xx:xx:xx ether daddr xx:xx:xx:xx:xx:xx
   ip saddr 192.168.0.1 ip daddr 255.255.255.255 ip dscp cs0
   ip ecn not-ect ip
   trace id 16767227 ip filter input rule nftrace set 0 (verdict continue)
   trace id 16767227 ip filter input verdict continue
   trace id 16767227 ip filter input
