[Bridge] [PATCH net-next] netfilter: nft_meta: Fix build error

[YueHaibing]

If NFT_BRIDGE_META is y and NF_TABLES is m, building fails:

net/bridge/netfilter/nft_meta_bridge.o: In function `nft_meta_bridge_get_init':
nft_meta_bridge.c:(.text+0xd0): undefined reference to `nft_parse_register'
nft_meta_bridge.c:(.text+0xec): undefined reference to `nft_validate_register_store'
