Change v_usecount & v_writecount from a short to an int. As shorts they
can and will overflow on large machines - especially on machines with
filesystems with lots of files (like netnews servers), and the result
is a "free vnode isn't" panic or worse.
This fixes one of the causes of these panics that I've been experiancing on
wcarchive.
