selinux: use GFP_ATOMIC under spin_lock 

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()
