->aml_end and ->pkg_end are same here.

acpi_ps_init_scope is only called in acpi_ds_init_aml_walk which set
aml_end and pkg_end the same.

acpi_ds_init_aml_walk(...)
{
    ....
    walk_state->parser_state.aml_end =
            walk_state->parser_state.pkg_end = aml_start + aml_length;
    .....

    status = acpi_ps_init_scope(&walk_state->parser_state, op);
    .....
}
