Bug fix from Eric Norum:

After weeks of trying to figure why my RTEMS/KASQ server crashes now
and then I found a nasty bug I introduced in adding multiple-driver
support to libio. The bug only affects `add-on' driver classes (like
the networking code). Old-style file descriptors were not affected.

The bug cleared 32 bytes of memory (unspecified location) whenever a
`close' of a socket was performed! I was clearing an IOP I hadn't
allocated -- and the pointer wasn't initiallized, either!
