i.MX: Fix FEC/ENET receive funtions
The actual imx_eth_enable_rx() function is buggy. It updates s->regs[ENET_RDAR] after calling qemu_flush_queued_packets(). qemu_flush_queued_packets() is going to call imx_XXX_receive() which itself is going to call imx_eth_enable_rx(). By updating s->regs[ENET_RDAR] after calling qemu_flush_queued_packets() we end up updating the register with an outdated value which might lead to disabling the receive function in the i.MX FEC/ENET device. This patch change the place where the register update is done so that the register value stays up to date and the receive function can keep running.
