Martin Schwidefsky d4f2a840c7 s390/vtime: correct idle time calculation ...

commit 4560e7c331 upstream.

Use the ACCESS_ONCE macro for both accesses to idle->sequence in the
loops to calculate the idle time. If only one access uses the macro,
the compiler is free to cache the value for the second access which
can cause endless loops.
