Drivers: hv: vmbus: do not mark HV_PCIE as perf_device

commit 238064f13d057390a8c5e1a6a80f4f0a0ec46499 upstream.

The pci-hyperv driver's channel callback hv_pci_onchannelcallback() is not
really a hot path, so we don't need to mark it as a perf_device, meaning
with this patch all HV_PCIE channels' target_cpu will be CPU0.
