Vitaly Kuznetsov 837d741ea2 PCI: hv: Handle all pending messages in hv_pci_onchannelcallback() ... When we have an interrupt from the host we have a bit set in event page indicating there are messages for the particular channel. We need to read them all as we won't get signaled for what was on the queue before we cleared the bit in vmbus_on_event(). This applies to all Hyper-V drivers and the pass-through driver should do the same. I did not meet any bugs; the issue was found by code inspection. We don't have many events going through hv_pci_onchannelcallback(), which explains why nobody reported the issue before. While on it, fix handling non-zero vmbus_recvpacket_raw() return values by dropping out. If the return value is not zero, it is wrong to inspect buffer or bytes_recvd as these may contain invalid data.
