f3d8e7d9ab hyperv/vmbus: Fix the multi-channel revoking on vmbus side.
- Reference count the sub-channel when channel offer message is
  processed, so that immediate rescind message on the same channel
  will not race sub-channel open on driver side.
- Drop the above reference when sub-channel is closed, this closely
  mimics the hypervisor's reaction when primary channel is closed
  on the VM side.  No drivers use sub-channel after primary channel
  is closed.

db1aaff31a hyperv/vmbus: Fix the primary channel revoking on vmbus side.
Drivers can now use vmbus_chan_{is_revoked,set_orphan,unset_orphan}() and
vmbus_xact_ctx_orphan() to fix their attach/detach DEVMETHODs for revoked
primary channels.

3ddc289828 hyperv/vmbus: Use different struct for RX/TX bufring.
So that they can use suitable MP synchronization mechanism.

While I'm here change the bufring init/read/write function names.
