[Qemu-devel] [PATCH] fix the return value of rtl8139_can_receive()

[Wen Congyang]

If rtl8139_can_receive() returns 1, it means that the nic can receive packet,
otherwise, it means the nic can not receive packet.

If !s->clock_enabled or !rtl8139_receiver_enabled(s), it means that the nic
can not receive packet. So the return value should be 0, not 1.
