Maurizio Lombardi 01a4cc4d0c bnx2fc: do not add shared skbs to the fcoe_rx_list
In some cases, the fcoe_rx_list may contains multiple instances
of the same skb (the so called "shared skbs").

the bnx2fc_l2_rcv thread is a loop that extracts a skb from the list,
modifies (and destroys) its content and then proceed to the next one.
The problem is that if the skb is shared, the remaining instances will
be corrupted.

The solution is to use skb_share_check() before adding the skb to the
fcoe_rx_list.
