wifi: ath12k: Free allocated external IRQs on request_irq() failure

Browse source

When external IRQ configuration fails, the driver does not release all
IRQs that were successfully requested before the failure. This can leak
IRQ resources during probe failure.

Free previously requested external IRQs when external IRQ configuration
fails.

Also remove the NAPI instance with netif_napi_del() before freeing the
associated netdev to properly clean up the NAPI resources.

Store the IRQ number only after request_irq() succeeds to avoid recording
an IRQ that was not successfully requested.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.6-01243-QCAHKSWPL_SILICONZ-1
