fcoe:Fix incorrect use of non wrapper version of skb_buff helper function in fcoe_percpu_recieve_thread

This fixes the incorrect use of the non wrapper version of the function skb_dequeue in fcoe_percpu_receive_thread to use the wrapper version as we need to protect avoid other users from concurrently access on the sk_buff_head tmp used as the link list head for this call to skb_queue.

The sk_buff_head tmp is a local reference on the stack, so not accessed concurrently from anywhere. It's set with skb_queue_splice_init while holding the lock for the real fcoe_rx_list, specifically to batch process without repeatedly taking and dropping the lock.

Nak, flawed reasoning for justification.
