[PATCH ipsec 0/2] xfrm: fixes for xfrm_state_find under preemption

[Sabrina Dubroca <sd@queasysnail.net>]

While looking at the pcpu_id changes, I found two issues that can
happen if we get preempted and the cpu_id changes. The second patch
takes care of both problems. The first patch also makes sure we don't
use state_ptrs uninitialized, which could currently happen. syzbot
seems to have hit this issue [1].

  xfrm: state: initialize state_ptrs earlier in xfrm_state_find
  xfrm: state: use a consistent pcpu_id for xfrm_state_find
