The host keeps sending heartbeat packets independent of guest responding to
them. In some situations, there might be multiple heartbeat packets pending in
the ring buffer. Don't lose them, read them all.

hv_pci_devices_present is called in hv_pci_remove when we remove a PCI device
from host (e.g. by disabling SRIOV on a device). In hv_pci_remove, the bus is
already removed before the call, so we don't need to rescan the bus in the
workqueue schedule
From: Long Li <lon...@microsoft.com>
A PCI_EJECT message can arrive at the same time we are calling
pci_scan_child_bus in the workqueue for the previous PCI_BUS_RELATIONS message,
in this case we could potentailly modify the bus from two places. Properly lock
the bus access.

When sense message is present on error, we should pass along to the upper layer
to decide how to deal with the error. This patch fixes connectivity issues with
Fiber Channel devices.
