qed: iWARP - Fix tc for MPA ll2 connection

[ Upstream commit cb94d52b ]

The driver needs to assign a lossless traffic class for the MPA ll2
connection to ensure no packets are dropped when returning from the
driver as they will never be re-transmitted by the peer.

Fixes: ae3488ff ("qed: Add ll2 connection for processing unaligned MPA packets")
