zio_root() has no arguments for ready callback or parent ZIO. Except one recent case in ZIL code if root ZIOs ever have a parent it is also a root ZIO. It means we do not need READY pipeline stage for them, which takes some time to process, but even more time to wait for the children and be woken by them, and both for no good reason. The most visible effect of this change is that it avoids one taskq wakeup per ZIL block written, previously used to run zio_ready() for lwb_root_zio and skipped now.
