Isn't it effectively bitnap_from_arr32() ?

Ditto.

With bitmap_set_value() we are also specifying the offset (or start)
position too. so that the remainder of the array remains unaffected. I
think it would not be feasible to use bitmap_from/to_arr32()  here.

You have hard coded start and nbits parameters to 32. How is it not the
same?

Would these four lines become something like this:

        bitmap_from_arr32(old, state, 64);
        ...
        bitmap_from_arr32(new, state, 64);

This is my understanding, but I might miss something. I mean driver
specifics that make my proposal incorrect.
