  Modified files:
    sys/fs/nullfs        null_subr.c 
  Log:
   - 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.
