Xin LI 290a1ba9a4 The current ZFS code expects ddt_zap_count to always succeed by asserting ... the underlying zap_count() to return no errors. However, it is possible that the pool reaches to such a state where zap_count would return error, leading to panics when a pool is imported. This commit changes the ddt_zap_count to return error returned from zap_count and handle the error appropriately. With this change, it's now possible to let zpool rollback damaged transaction groups and import the pool.
