25641fc705 hyperv/hn: Fix primary channel revocation 
Since hypervisor will not drain the TX bufring, once the channels are
revoked:
- Setup vmbus orphan handler properly.
- Make sure that suspension will not wait the TX bufring draining
  forever.
- GC the pending TX descs on detach path, before freeing the busdma
  stuffs.

dc13fee60c hyperv/hn: Implement RNDIS multi-packet message support. 
Currently, it is only applied to packet sent through chimney sending
buffers.  Not enabled by default yet.

This one gives 20%~30% performance boost for non-TSO usage in both
bit/packet rate tests and nginx performance test.
