In some scenarios, a split IO can immediately complete. For
example, a very large unmap operation to a newly thin-provisioned
blob has no operations to perform, so the batch for its operation
immediately completes.
But if it immediately completes, we can't recursively submit
the next split IO. So use variables in the context structure
to detect when an operation immediately completes, to allow
it to unwind and submit the next operation without recursing.
Fixes issue #2347.
