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.

Since the target received SRR, it was able to send the XFER_RDY and the the original IO request completed successfully. In this condition ABTS was not sent during bnx2fc_srr_compl(). Fix this by first checking for ELS timeout and issue ABTS before checking if original IO request is complete.
