net/key/af_key.c: In function ‘pfkey_spddelete’:
net/key/af_key.c:2359: warning: ‘pol_ctx’ may be used uninitialized in
this function

When CONFIG_SECURITY_NETWORK_XFRM isn't set,
security_xfrm_policy_alloc() is an inline that doesn't set pol_ctx, so
this seemed like the easiest fix short of using *uninitialized_var(pol_ctx).
