Fix the resource.fs.zfs.statechange message

It had a number of problems:

* It was only being emitted on a transition to the HEALTHY state.  That
  made it impossible for zfsd to take actions based on drives getting
  sicker.
* It compared the new state to vdev_prevstate, which is the state that
  the vdev had the last time it was opened.  That doesn't make sense,
  because a vdev can change state multiple times without being reopened.
* vdev_set_state contains logic that will change the device's new state
  based on various conditions.  However, the statechange event was being
  posted _before_ that logic took effect.  Now it's being posted after.
