wifi: iwlwifi: pcie: synchronize IRQs before NAPI



When we want to synchronize the NAPI, which was added in
commit 5af2bb31 ("wifi: iwlwifi: call napi_synchronize()
before freeing rx/tx queues"), we also need to make sure we
can't actually reschedule the NAPI. Yes, this happens while
interrupts are disabled, but interrupts may still be running
or pending. Also call iwl_pcie_synchronize_irqs() to ensure
we won't reschedule the NAPI.

Fixes: 4cf2f590 ("iwlwifi: queue: avoid memory leak in reset flow")
