net: fec: improve fec_enet_rx_queue()

This patch has made the following adjustments to fec_enet_rx_queue().

1. The function parameters are modified to maintain the same style as
subsequently added XDP-related interfaces.

2. Some variables are initialized at the time of declaration, and the
order of local variables is updated to follow the reverse xmas tree
style.

3. Replace variable cbd_bufaddr with dma.
