net: fec: improve XDP_TX performance
As suggested by Jesper and Alexander, we can avoid converting xdp_buff
to xdp_frame in case of XDP_TX to save a bunch of CPU cycles, so that
we can further improve the XDP_TX performance.
Before this patch on i.MX8MP-EVK board, the performance shows as follows.

proto 17: 352672 pkt/s
proto 17: 353912 pkt/s
proto 17: 354219 pkt/s
After applying this patch, the performance is improved.
