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: c1bacbae8192 ("genirq: Provide irq_request/release_resources chip callbacks")
