scsi: fix bnx2i build errors

bnx2i should depend on NET since it selects SCSI_ISCSI_ATTRS, which
depends on NET.

Also move the dependencies together.

The "depends" change fixes multiple build errors when CONFIG_NET is
not enabled:
ERROR: "skb_trim" [drivers/scsi/scsi_transport_iscsi.ko] undefined!
ERROR: "netlink_kernel_create" [drivers/scsi/scsi_transport_iscsi.ko] undefined!
