Jeff Roberson 9c12e63100 - Assert that the lowervp is locked in null_hashget().
- Simplify the logic dealing with recycled vnodes in null_hashget() and
   null_hashins().  Since we hold the lower node locked in both cases
   the null node can not be undergoing recycling unless reclaim somehow
   called null_nodeget().  The logic that was in place was not safe and
   was essentially dead code.
