powerpc/kernel: Avoid preemption check in iommu_range_alloc()
Replace the __this_cpu_read() with raw_cpu_read() in
iommu_range_alloc(). Otherwise we get a warning about using
__this_cpu_read() in preemptible code:
BUG: using __this_cpu_read() in preemptible
caller is iommu_range_alloc+0xa8/0x3d0
Preemption doesn't need to be disabled since according to the comment
any CPU can safely use any IOMMU pool.
