Subject: [PATCH] zil_close: don't try to deallocate on-disk blocks

If we're force-exporting or failed then there's no guarantee the IO will
get anywhere. If its a clean shutdown then that's actually the lead
block and it'll be sorted out during replay or next txg.

(cherry picked from commit 01e04a4eef7811a31a6258c99d0cc51217732758)
