  Lock protection is needed during the vhost notifies the application of
device readiness, so the first patch is to add lock protection. After
performing locking, existed async vhost registration functions will cause
deadlock, as they acquire lock too. So the second patch is to provide
unsafe registration functions to support calling within vhost callback
functions.

  vhost: fix lock on device readiness notification
  vhost: add thread unsafe async registration functions
