If 'irq_of_parse_and_map()' or 'of_address_to_resource()' fail, 'err' is
known to be 0 at this point.
So return -ENODEV instead in the first case and propagate the error
returned by 'of_address_to_resource()' in the 2nd case.
While at it, turn a 'err != 0' test into an equivalent 'err' to be more
consistent.
