genirq: Release resources in __setup_irq() error path

commit fa07ab72cbb0d843429e61bf179308aed6cbe0dd upstream.

In case __irq_set_trigger() fails the resources requested via
irq_request_resources() are not released.

Add the missing release call into the error handling path.

Fixes: c1bacbae ("genirq: Provide irq_request/release_resources chip callbacks")
