ENGR00170784 - FEC : dma skb buffer map is not used rightly.

Enable "CONFIG_DMA_API_DEBUG" in kernel, and system print:

DMA-API: device driver tries to free DMA memory it has not
allocated [device address=0x0000000046688020]...[<80222494>]
(debug_dma_unmap_page+0x8c/0x98) from [<802a36a0>]
(fec_enet_interrupt+0x430/0x5ac)

Correct the usage of "dma_map_single" function.
