netfilter: nft_socket: fix an unused variable warning
The variable is only used in an #ifdef, causing a harmless warning:
net/netfilter/nft_socket.c: In function 'nft_socket_init':
net/netfilter/nft_socket.c:137:27: error: unused variable 'level' [-Werror=unused-variable]
137 | unsigned int len, level;
| ^~~~~
Move it into the same #ifdef block.
Fixes: e0bb96db96f8 ("netfilter: nft_socket: add support for cgroupsv2")
