The irq_of_parse_and_map() function returns 0 on failure, and does not
return a negative value anyhow, so never enter this conditional branch.

This one fixes a commit that moved away from platform APIs!
The change was introduced in 2014 in the commit f6a8eaca0ea1
("drm/msm/mdp5: use irqdomains"). I can suspect that at that time
platform irq code wasn't fully compatible with IRQ domains.
