[buggy index field handling] [patch]

Hi Andy,

There is a funny bug in acpi/executer/exfldio.c::acpi_ex_field_datum_io

When the field come from an indexed one, we read all the time from the
address obj_desc->index_field.value
Unfortunately, this is wrong, since the correct address is
obviously &obj_desc->index_field.value + field_datum_byte_offset
