platform_get_irq() only return non-zero irq number on success, or
negative error number on failure.

There is no need to check the return value of platform_get_irq()
to determine the return value of dwc3_otg_get_irq(), removing
them to solve this problem.

Hi Thinh,

I'm checking in about my patch submission for usb dwc3 that was 
"ack'ed" on 3/25, but hasn't been merged into the subtree yet. 
Could you please provide me with an update on its status and let 
me know if there are any issues or concerns that need to be addressed?

It's not in my queue anywhere, so it needs to be resent if anyone wants
this applied.
