netfilter: bridge: make NF_TABLES_BRIDGE tristate
The new nft_meta_bridge code fails to link as built-in when NF_TABLES is a loadable module. net/bridge/netfilter/nft_meta_bridge.o: In function `nft_meta_bridge_get_eval': nft_meta_bridge.c:(.text+0x1e8): undefined reference to `nft_meta_get_eval' net/bridge/netfilter/nft_meta_bridge.o: In function `nft_meta_bridge_get_init': nft_meta_bridge.c:(.text+0x468): undefined reference to `nft_meta_get_init' nft_meta_bridge.c:(.text+0x49c): undefined reference to `nft_parse_register' nft_meta_bridge.c:(.text+0x4cc): undefined reference to `nft_validate_register_store' net/bridge/netfilter/nft_meta_bridge.o: In function `nft_meta_bridge_module_exit': nft_meta_bridge.c:(.exit.text+0x14): undefined reference to `nft_unregister_expr' net/bridge/netfilter/nft_meta_bridge.o: In function `nft_meta_bridge_module_init': nft_meta_bridge.c:(.init.text+0x14): undefined reference to `nft_register_expr' net/bridge/netfilter/nft_meta_bridge.o:(.rodata+0x60): undefined reference to `nft_meta_get_dump' net/bridge/netfilter/nft_meta_bridge.o:(.rodata+0x88): undefined reference to `nft_meta_set_eval' This can happen because the NF_TABLES_BRIDGE dependency itself is just a 'bool'. Make the symbol a 'tristate' instead so Kconfig can propagate the dependencies correctly.
