Alberto Garcia ef7a6a3c2a qemu-iotests: Test removing a throttle group member with a pending timer
A throttle group can have several members, and each one of them can
have several pending requests in the queue.

The requests are processed in a round-robin fashion, so the algorithm
decides the drive that is going to run the next request and sets a
timer in it. Once the timer fires and the throttled request is run
then the next drive from the group is selected and a new timer is set.

If the user tried to remove a drive from a group and that drive had a
timer set then the code was not taking care of setting up a new timer
in one of the remaining members of the group, freezing their I/O.

This problem was fixed in 6fccbb475b,
and this patch adds a new test case that reproduces this exact
scenario.
