[PATCH net] qed: Fix an error code qed_ll2_start_xmit()

[Dan Carpenter]

We accidentally deleted the code to set "rc = -ENOMEM;" and this patch
adds it back.

Fixes: d2201a21598a ("qed: No need for LL2 frags indication")

I'm not totally sure about this patch.  Please review it carefully.

There are four callers of this function: qedi_data_avail(), qedf_xmit(),
qedf_fcoe_send_vlan_req() and qedf_fip_send().  Only qedi_data_avail()
checks the error code, and if it sees an error it calls kfree_skb().
