genirq: Release resources in __setup_irq() error path

Browse Source 
commit fa07ab72cb 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: c1bacbae81 ("genirq: Provide irq_request/release_resources chip callbacks")
