riastradh e7c9fe41a3 audio(4): Fix bug in detaching audio16 and beyond. 
The minor numbers have only four bits for the unit number, so unit
numbers past 15 can't be represented as is.  Attempting to revoke
them was once harmless, when the system made no attempt to avoid
open/detach races; now it crashes because vdevgone assumes that the
minor number can be mapped back to an autoconf device, but it's the
wrong one.  With this change, we stop trying to revoke units beyond
15, because they can't be opened anyway (which may be a bug in its
own right, requiring expansion of the minor number encoding!).
