Function mac_syncache_destroy

freebsd/security/mac/mac_inet.c:446–455

* These functions really should be referencing the syncache structure * instead of the label. However, due to some of the complexities associated * with exposing this syncache structure we operate directly on its label * pointer. This should be OK since we aren't making any access control * decisions within this code directly, we are merely allocating and copying * label storage so we can p

 * the syncache code might create.
