  Log:
  getnewvnode: Weaken the panic "cleaned vnode isn't" to a warning.
  
    Discussion: this panic (or waning) only occurs when the kernel is
    compiled with INVARIANTS.  Otherwise the problem (which means that
    the vp->v_data field isn't NULL, and represents a coding error and
    possibly a memory leak) is silently ignored by setting it to NULL
    later on.
  
    Panicking here isn't very helpful: by this time, we can only find
    the symptoms.  The panic occurs long after the reason for "not
    cleaning" has been forgotten; in the case in point, it was the
    result of severe file system corruption which left the v_type field
    set to VBAD.  That issue will be addressed by a separate commit.
