[PATCH] Smack: fix netfilter Makefile entry

[Arnd Bergmann]

The newly added Smack support for netfilter secmark has its own
Kconfig symbol, but the actual implementation is conditionally
built on another symbol.

It is possible for CONFIG_NETFILTER and SECURITY_SMACK to both
be enabled, but NETWORK_SECMARK to be disabled, in which case
we get a build error:

../security/smack/smack_netfilter.c: In function 'smack_ipv6_output':
../security/smack/smack_netfilter.c:36:6: error: 'struct sk_buff' has no member named 'secmark'
   skb->secmark = skp->smk_secid;
      ^
../security/smack/smack_netfilter.c: In function 'smack_ipv4_output':
../security/smack/smack_netfilter.c:55:6: error: 'struct sk_buff' has no member named 'secmark'
   skb->secmark = skp->smk_secid;
      ^

This changes the Makefile to use the correct Kconfig symbol.
