This specific clock_step_next() call is done immediately after
resetting the timer device, so there *is* no pending interrupt.
(That's why it's a problem -- it says "step the clock forward
to the next pending timer expiry", and there is no next
pending timer expiry.)

There's another clock_step_next() just after the context
in this patch, and that one is fine, because it's after
the test enables the timer and so there will be a
next pending expiry to step forward to.
