The code currently relies on refcounting to disable IRQs from within the IRQ handler and re-enabling them again after the tasklet has run. However, due to race conditions sometimes the IRQ handler might be called twice, or the tasklet may not run at all (if interrupted in the middle of a reset). This can cause nasty imbalances in the irq-disable refcount which will get the driver permanently stuck until the entire radio has been stopped and started again (ath_reset will not recover from this). Instead of using this fragile logic, change the code to ensure that running the irq handler during tasklet processing is safe, and leave the refcount untouched.
