[PATCH net v4 0/5][pull request] ice: fix stats array overflow via proper realloc

[Tony Nguyen <anthony.l.nguyen@intel.com>]

Przemek Kitszel says:

Fix OOB access to the stats arrays.

The first three commits are simple refactors to make the rest smaller,
the fourth one untangles the logic/lifetime of the stats array entries,
then we have the final fix by Michal for VF OOB access to the stats array.

Michal's fix was made prior to the rest, I have only slightly changed it
to base it on top of the pre-work commits, that should resolve all the
corner/error cases reported by AI.

The series was made anew vs the [v2], but the goal and spirit is similar,
but I have started from beginning instead of playing whack-a-mole with
yet another corner cases. We are also back to [v0] by Michal, as it turned
out to be more elegant finish with my first four patches already intact.
