drivers/net/ethernet/broadcom/cnic.c: remove invalid reference to list iterator variable 

If list_for_each_entry, etc complete a traversal of the list, the iterator
variable ends up pointing to an address at an offset from the list head,
and not a meaningful structure.  Thus this value should not be used after
the end of the iterator.  There does not seem to be a meaningful value to
provide to netdev_warn.  Replace with pr_warn, since pr_err is used
elsewhere.

This problem was found using Coccinelle (http://coccinelle.lip6.fr/).
