net: fec: remove useless fec_enet_reset_skb()

Browse Source 
This patch is a cleanup for fec driver. The fec_enet_reset_skb()
is used to free skb buffers for tx queues and is only invoked in
fec_restart(). However, fec_enet_bd_init() also resets skb buffers
and is invoked in fec_restart() too. So fec_enet_reset_skb() is
redundant and useless.
