cnic, bnx2i: Fix bug on some bnx2x devices that don't support iSCSI
On some bnx2x devices, iSCSI is determined to be unsupported only after
firmware is downloaded. We need to check max_iscsi_conn again after
NETDEV_UP and block iSCSI init operations. Without this fix, iscsiadm
can hang as the firmware will not respond to the iSCSI init message.
