bjk 7280c1da39 Check for mismatched vref()/vdrop() ...

Assert that the hold count has not fallen below the use count, a situation
that would only happen when a vref() (or similar) is erroneously paired
with a vdrop().  This situation has not been observed in the wild, but
could be helpful for someone implementing a new filesystem.
