iommu/arm-smmu-v3: Replace sort_nonatomic() with sort()

Browse Source 
The number of master->num_streams per master device is typically very
small in practice. Sorting this array takes a very small amount of
time, so there is no practical risk of triggering a soft lockup that
would necessitate calling cond_resched() during the sort.

Replace sort_nonatomic() with the standard sort(). Since this is the
only remaining in-tree caller of sort_nonatomic(), this change paves
the way to eventually remove the unused sort_nonatomic() API from the
core library.
