SVN rev 199435 on 2009-11-17 20:49:26Z by mav
MFC r198748, r198782:
Fix reference counting bug, when device unreferenced before
invalidated. To do it, do not handle validity flag as another
reference, but explicitly modify reference count each time flag is
modified.
The async callback could free the device. If it is a broadcast async,
it doesn't hold device reference, so take our own reference.
