Log Message:
Clean up vnode lock operations:

 - VOP_LOCK(vp, flags): Limit the set of allowed flags to LK_EXCLUSIVE,
   LK_SHARED and LK_NOWAIT.  LK_INTERLOCK is no longer allowed as it
   makes no sense here.

- VOP_ISLOCKED(vp): Remove the for some time unused return value
  LK_EXCLOTHER.  Mark this operation as "diagnostic only".
  Making a lock decision based on this operation is no longer allowed.

Discussed on tech-kern.
