net: xilinx: axiethernet: Fix code checker warnings

Remove map_dma_q_irq() redundant definition and also reduce the scope of
axienet_queue_xmit function. This patch fixes below sparse warnings.

drivers/net/ethernet/xilinx/xilinx_axienet_main.c: At top level:
drivers/net/ethernet/xilinx/xilinx_axienet_main.c:1004:5: warning: no previous
prototype for ‘axienet_queue_xmit’ [-Wmissing-prototypes]
int axienet_queue_xmit(struct sk_buff *skb, struct net_device *ndev,
u16 map)
