Zijun Hu 2396eefa07 genirq/devres: Don't free interrupt which is not managed by devres ...

If devres_destroy() does not find a matching devres entry, then
devm_free_irq() emits a warning and tries to free the interrupt.

That's wrong as devm_free_irq() should only undo what devm_request_irq()
set up.

Replace devres_destroy() with a call to devres_release() which only invokes
the release function (free_irq()) in case that a matching devres entry was
found.
