selinux: use GFP_ATOMIC under spin_lock
commit 4502403dcf8f5c76abd4dbab8726c8e4ecb5cd34 upstream.
The call tree here is:
sk_clone_lock() <- takes bh_lock_sock(newsk);
xfrm_sk_clone_policy()
__xfrm_sk_clone_policy()
clone_policy() <- uses GFP_ATOMIC for allocations
security_xfrm_policy_clone()
security_ops->xfrm_policy_clone_security()
selinux_xfrm_policy_clone()
