Device name actually uses LUID index only. Not an entire LUID. IfType

This also introduces a proper queueing and refcounting system, which
should increase performance and allow for IRP cancelation.

Terminate device connection on NDIS pause
...
If device connection is not terminated on NDIS pause, the driver doesn't
unload when adapter is disabled. This also prevents driver updates
without reboot.

Fix ActiveNBLCount management in TunDispatchWrite()
...
The ActiveNBLCount must be bumped _before_ adapter state is checked.
Otherwise, there is a window of code that may allow adapter transition
from pausing to paused state, followed by a
NdisMIndicateReceiveNetBufferLists() call.
