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

Browse source

When CE 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 the previously requested CE IRQs before returning from the error
path to ensure that partially initialized IRQ resources are properly
cleaned up during probe failure.

Factor out the CE IRQ cleanup into a helper to reuse the cleanup logic
during both error handling and driver teardown.

Also free CE IRQs when external IRQ configuration fails, before
returning from the error path.

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