Log:
SVN rev 187715 on 2009-01-26 14:21:00Z by kib
The kernel may do unbalanced calls to fifo_close() for fifo vnode,
without corresponding number of fifo_open(). This causes assertion
failure in fifo_close() due to vp->v_fifoinfo being NULL for kernel
with INVARIANTS, or NULL pointer dereference otherwise. In fact, we may
ignore excess calls to fifo_close() without bad consequences.
Turn KASSERT() into the return, and print warning for now.
