EDAC/aspeed: Fix handling of platform_get_irq() error 

[ Upstream commit afce699694 ]

platform_get_irq() returns a negative error number on error. In such a
case, comparison to 0 would pass the check therefore check the return
value properly, whether it is negative.

 [ bp: Massage commit message. ]
