throttle: Correct access to wrong BlockBackendPublic structures
In 27ccdd52598290f0f8b58be56e235aff7aebfaf3 the throttling fields were
moved from BlockDriverState to BlockBackend. However in a few cases
the code started using throttling fields from the active BlockBackend
instead of the round-robin token, making the algorithm behave
incorrectly.
This can cause starvation if there's a throttling group with several
drives but only one of them has I/O.
