Matching network device based on MAC address is problematic
since a non VF network device can be creted with a duplicate MAC
address causing confusion and problems. The VMBus API does provide
a serial number that is a better matching method.

For unsupported device types, the vmbus channel ringbuffer is never

or cause a kernel OOPS.

This set of patches addresses two set of fixes. First it backs out
the common callback model which was merged in net-next without
completing all the review feedback or getting maintainer approval.
Then it fixes the transparent VF management code to handle network
namespaces.

The get/put functions were taking a reason code. This appears to be
a debug infrastructure that is no longer used.
Move the functions to start of file to eliminate need for
forward declaration. Forward declarations are discouraged on
Linux.

Use refcount instead of atomic for the reference counting
on bus. Refcount is safer because it handles overflow correctly.

These are minor code cleanups found while reviewing and implementing
other things in Hyper-V PCI host driver.
