Coverity complains about a possible NULL pointer dereference. This is impossible, but it suspects it because we do a NULL check against `spa->spa_root_vdev`. This NULL check was never necessary and makes the code harder to understand, so we drop it. In particular, we dereference `spa->spa_root_vdev` when `new_state != POOL_STATE_UNINITIALIZED && !hardforce`. The first is only true when spa_reset is called, which only occurs under fault injection. The second is true unless `zpool export -F $POOLNAME` is used. Therefore, we effectively *always* dereference the pointer. In the cases where we do not, there is no reason to think it is unsafe. Therefore this change is safe to make.
