When Rx queues are configured during module init, NAPI is enabled while the Rx queue lock is held. However, since softirqs are not disabled, it is possible that and IRQ would fire and call iwl_pcie_rx_handle() which would also try to acquire the Rx lock. Prevent this by disabling softirqs during Rx queue configuration, as part of module init flow.
