[PATCH 1/4] staging: hv: Fix the code depending on struct vmbus_driver_context data order
The patch fixed the code depending on the exact order of fields in the
struct vmbus_driver_context, so the unused field drv_ctx can be removed,
and drv_obj doesn't have to be the second field in this structure.
