[PATCH 2/4] Drivers: hv: vmbus: do not mark HV_PCIE as perf_device

From: Dexuan Cui <decui@microsoft.com>

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.
