platform_get_irq() return negative value on failure, so null check of
priv->irq is incorrect. Fix it by comparing whether it is less than zero.

Thanks for the fix. Can we prefix the subject with "peci: aspeed:"? Just to
distinguish changes related to specific controller from the ones touching peci-
core.
