ACPI, APEI, Fix error return value in apei_map_generic_address()

From commit 6915564dc5a8 ("ACPI: OSL: Change the type of
acpi_os_map_generic_address() return value"),
acpi_os_map_generic_address() will return logical address or NULL
for error, but for ACPI_ADR_SPACE_SYSTEM_IO case, it should be also
return 0 as it's a normal case, but now it will return -ENXIO.

So check it out for such case to avoid einj module initialization
fail.
