Subject: [PATCH 13/14] PCI: hv: switch hv_compose_multi_msi_req_get_cpu() to using cpumask_next_wrap()

Calling cpumask_next_wrap_old() with starting CPU == nr_cpu_ids
is effectively the same as request to find first CPU, starting
from a given one and wrapping around if needed.

cpumask_next_wrap() is a proper replacement for that.
