savevm: Remove all the unneeded version_minimum_id_old (arm)

After commit 767adce2d, they are redundant.  This way we don't assign them
except when needed.  Once there, there were lots of cases where the ".fields"
indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (apart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.
