scsi: bnx2fc: Fix skb double free in bnx2fc_rcv()
[ Upstream commit 08c94d80b2da481652fb633e79cbc41e9e326a91 ]
skb_share_check() already drops the reference to the skb when returning
NULL. Using kfree_skb() in the error handling path leads to an skb double
free.
Fix this by removing the variable tmp_skb, and return directly when
skb_share_check() returns NULL.
Fixes: 01a4cc4d0cd6 ("bnx2fc: do not add shared skbs to the fcoe_rx_list")
