Merge branch 'xfrm: fixes for xfrm_state_find under preemption'

Sabrina Dubroca says:

====================
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].
