[IA64] another place to use for_each_cpu_mask() in arch/ia64
In arch/ia64 change the explicit use of a for-loop using NR_CPUS into the general for_each_online_cpu() construct. This widens the scope of potential future optimizations of the general constructs, as well as takes advantage of the existing optimizations of first_cpu() and next_cpu(), which is advantageous when the true CPU count is much smaller than NR_CPUS.
