PCI: hv: Take a const cpumask in hv_compose_msi_req_get_cpu()

Browse Source 
The cpumask that is passed to this function ultimately comes from
irq_data_get_effective_affinity_mask(), which was recently changed to
return a const cpumask pointer. The first level of functions handling
the affinity mask were updated, but not this helper function.

Fixes: 4d0b829881 ("genirq: Return a const cpumask from irq_data_get_affinity_mask")
