Wei Yongjun 1fe4c93fc7 scsi: bnx2fc: Fix skb double free in bnx2fc_rcv()
[ Upstream commit 08c94d80b2 ]

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.
