rS309085: hyperv/hn: Fix primary channel revocation

Summary

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.
