IB/qib: Fix interrupt mitigation
For SusieQ we need to write to the interrupt timer register before
updating the header queue head with interrupt count. This is to
ensure that the timer is enabled properly and a receive available
interrupt is delivered. Otherwise this interrupt can be lost if the
receiver header/eager queues are full before the timer is enabled.
