Subject: [PATCH 1/2] cxgb4: Add missing annotation for service_ofldq()

Sparse reports a warning at service_ofldq()

warning: context imbalance in service_ofldq() - unexpected unlock

The root cause is the missing annotation at service_ofldq()

Add the missing __must_hold(&q->sendq.lock) annotation
