spapr_llan: fix device reenabling
Normally, the "tap" device is polled by QEMU if a guest NIC can
receive packets. If a guest NIC is stopped during transfer (rmmod or
ifdown), it may still have packets in a queue which have to be send
to the guest before QEMU enables polling of a "tap" interface via
tap_update_fd_handler().
However the spapr_llan device was missing the qemu_flush_queued_packets()
call so the tap_send_completed() callback was never called and therefore
"tap" interface polling was not enabled ever.
The patch fixes this problem.
