When CONFIG_AUDIT is set, its CONFIG_NET dependency is also set, and the dev_get_by_index and init_net symbols (used by dump_common_audit_data) are found by the linker. dump_common_audit_data() should then failed to build when CONFIG_NET is not set. However, because the compiler is smart, it knows that audit_log_start() always return NULL when !CONFIG_AUDIT, and it doesn't build the body of common_lsm_audit(). As a side effect, dump_common_audit_data() is not built and the linker doesn't error out because of missing symbols. Let's only build lsm_audit.o when CONFIG_SECURITY and CONFIG_AUDIT are both set, which is checked with the new CONFIG_HAS_SECURITY_AUDIT. ipv4_skb_to_auditdata() and ipv6_skb_to_auditdata() are only used by Smack if CONFIG_AUDIT is set, so they don't need fake implementations. Because common_lsm_audit() is used in multiple places without CONFIG_AUDIT checks, add a fake implementation.
