Recent changes to solve inconsistencies in handling IRQ masks #ifdef
out the affinity field in irq_common_data for non-SMP configurations.
The current code in hyperv_irq_remapping_alloc() gets a compiler error
in that case.
Fix this by using the new irq_data_update_affinity() helper, which
handles the non-SMP case correctly.
