Fan Wu 2776e9c285 ipe: protect the dm-verity root hash with RCU
ipe_bdev_setintegrity() frees the old root hash when dm-verity publishes
a new one on ->preresume, while policy evaluation can still be
dereferencing it.

Protect the root hash with RCU. The evaluation path already runs under
rcu_read_lock().
