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.
