Frederic Weisbecker 8388d21468 sched/cputime, ia64: Fix incorrect start cputime assignment on task switch
On task switch we must initialize the current cputime of the next task
using the value of the previous task which got freshly updated.

But we are confusing that with doing the opposite, which should result
in incorrect cputime accounting.
