iwlagn: update write pointers in iwl_irq_tasklet()
Follow-up to "update write pointers for all tx queues after wakeup"; that patch changed iwl_irq_tasklet_legacy(), but not iwl_irq_tasklet(), so newer devices were not covered. Comments from original patch: Wakeup interrupt has been updating write pointers (indexes, actually) only for tx queues 0-5. This is adequate just for 3945, but inadequate for other devices, all of which have more tx queues. Now updating all tx/command queues, so device can be aware of all new tx and host commands enqueued while device was asleep. This can potentially improve data traffic bandwidth and/or latency.
