[PATCH v3] cxl: Make loop variable be 'i' instead of 'j'

[Konrad Rzeszutek Wilk]

.. otherwise people spend extra cycles looking for the
inner loop and wondering 'why j'?

This was an oversight when initial work was rebased
so let's fix it here.

v1: Initial posting
v2: Fix per Dan's request
v3: Duh, don't initialize i in the loop, but do it outside of it.
