intel: fix gen_sort_tags.py
The script was failing for me (python 3.8), not sure if this is a recent python version break or not as I don't know how often people have been running this script:
Processing ./gen9.xml... Traceback (most recent call last):
File "./gen_sort_tags.py", line 177, in <module>
main()
File "./gen_sort_tags.py", line 170, in main
genxml[:] = enums + sorted_structs.values() + instructions + registers
TypeError: can only concatenate list (not "odict_values") to list
Turning the odict into a list fixes it for me, and the resulting xml file are identical to before :)
Fixes: 903e142f ("genxml: add a sorting script")
