        sys/arch/xen/xen/xbdback_xenbus.c: revision 1.109

Fix a brain-o in a KASSERT that could cause a guest to panic a DIAGNOSTIC
kernel: to assert that an I/O is already in flight we want
xbdi_pendingreqs > 0, not xbdi_pendingreqs > 1

While there, fix an error path that could also cause a KASSERT to fire
or a state corruption: reset xio_need_bounce to 0 before calling
xbdback_io_error() when the bounce buffer is not fully set up.
