Subject: [ 070/175] SCSI: iscsi: fix setting of pid from netlink skb

3.3-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mike Christie <michaelc@...wisc.edu>

commit df1c7baba1b7b3053950f3845a6575aca47ba9ce upstream.

NETLINK_CREDS's pid now returns 0, so I guess we are supposed to
be using NETLINK_CB. This changed while the patch to export the
pid was getting merged upstream, so it was not noticed until both
the network and iscsi changes were in the same tree.
