irqchip/sunxi-nmi: Fix error check of of_io_request_and_map()
commit cfe199afefe6201e998ddc07102fc1fdb55f196c upstream.
The of_io_request_and_map() returns a valid pointer in iomem region or
ERR_PTR(), check for NULL always fails and may cause a NULL pointer
dereference on error path.
Fixes: 0e841b04c829 ("irqchip/sunxi-nmi: Switch to of_io_request_and_map() from of_iomap()")
