[kle2info] Trim the code in `kle2xy` (#8955)

* [kle2jinfo] use min/max instead of if

This is a slight change.
Before, the key_skel would keep the invalid value for future keys.
I think this is what was actually intended.

* [kle2info] calculate x

x is the current_x * key_size + (key_size/2)
y is the current_y * key_size + (key_size/2)

no reason to track both
