commit 9c516e0e4554e8f26ab73d46cbc789d7d8db664d upstream.
The recent change to make insert range an atomic operation used the
incorrect transaction rolling mechanism. The explicit transaction
roll does not finish deferred operations. This means that intents
for rmapbt updates caused by extent shifts are not logged until the
final transaction commits. Thus if a crash occurs during an insert
range, log recovery might leave the rmapbt in an inconsistent state.
This was discovered by repeated runs of generic/455.
Update insert range to finish dfops on every shift iteration. This
is similar to collapse range and ensures that intents are logged
with the transactions that make associated changes.
