Glauber Costa 0b8b5abf16 commitlog: acquire semaphore earlier ...

Recently we have changed our shutdown strategy to wait for the
_request_controller semaphore to make sure no other allocations are
in-flight. That was done to fix an actual issue.

The problem is that this wasn't done early enough. We acquire the
semaphore after we have already marked ourselves as _shutdown and
released the timer.

That means that if there is an allocation in flight that needs to use a
new segment, it will never finish - and we'll therefore neve acquire
the semaphore.

Fix it by acquiring it first. At this point the allocations will all be
done and gone, and then we can shutdown everything else.
