The util module expects that the util channels are fully initialized
when the module loads. To deal with the race condition which can result
in a NULL pointer dereferencing if the util module were to load before

code was introduced in the vmbus driver to ensure that all the
util channels were fully initialized before returning from the load
of the vmbus driver. This solution has several problems: if for whatever
reason, any util channel were to fail to initialize, vmbus driver would
wait indefinitely. We deal with this synchronization issue very differently
in this patch.

The OSD layer was a wrapper around native interfaces
adding little value and was infact buggy -
refer to the osd_wait.patch for details.
This patch gets rid of the OSD abstraction.
