Subject: cxgb4: Add missing annotation for service_ofldq()
Patch-mainline: v5.7-rc5
Git-commit: cae9566acb1a4533ca85b63f7ac0cc7ebe4a0c30
References: jsc#SLE-15131

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
