The current check of nvec < minvec for nvec returned from
platform_irq_count() will not detect a negative error code in nvec.
This is because minvec is unsigned, and, as such, nvec is promoted to
unsigned in that check, which will make it a huge number (if it contained
-EPROBE_DEFER).
In practice, an error should not occur in nvec for the only in-tree
user, but add a check anyway.

I hope that this can go through either irqchip or driver/core trees, thanks!
I'll take it, thanks.
