Mark Johnston f0317f868b Simplify unp_disconnect() callers.
In all cases, PCBs are unlocked after unp_disconnect() returns.  Since
unp_disconnect() may release the last PCB reference, callers may have to
bump the refcount before the call just so that they can release them
again.

Change unp_disconnect() to release PCB locks as well as connection
references; this lets us remove several refcount manipulations.  Tighten
assertions.
