[PATCH net v5 0/6] ice: fix stats array overflow via proper realloc

[Przemek Kitszel <przemyslaw.kitszel@intel.com>]

Fix OOB access to the stats arrays.

The first commit (new in v5) fixes stats code against VSI_CHNL case (ADQ).

Next three commits are simple refactors to make the rest smaller,
the fifth one untangles the logic/lifetime of the stats array entries,
then we have the final fix for OOB access to the stats array (combined
for both PF and VF VSIs.

v5 handles now also the PF VSI stats resizes better, fixing devlink reload
issue reported in v4 by Clashiko.
