Chunwei Chen c7a4255f12 Fix zil replay panic when TX_REMOVE followed by TX_CREATE ... If TX_REMOVE is followed by TX_CREATE on the same object id, we need to make sure the object removal is completely finished before creation. The current implementation relies on dnode_hold_impl with DNODE_MUST_BE_ALLOCATED returning ENOENT. While this check seems to work fine before, in current version it does not guarantee the object removal is completed. We fix this by checking if DNODE_MUST_BE_FREE returns successful instead. Also add test and remove dead code in dnode_hold_impl.
