This reverts commit 6cd4a78d962bebbaf8beb7d2ead3f34120e3f7b2. inet/inet6->create() implementations have been fixed to explicitly NULL the allocated sk object on error. A warning was put in place to make sure any future changes will not leave a dangling pointer in pf->create() implementations. So this code is now redundant.
