octeontx2-pf: mcs: Fix shared counters logic
[ Upstream commit 9bdfe61054fb2b989eb58df20bf99c0cf67e3038 ]
Macsec stats like InPktsLate and InPktsDelayed share
same counter in hardware. If SecY replay_protect is true
then counter represents InPktsLate otherwise InPktsDelayed.
This mode change was tracked based on protect_frames
instead of replay_protect mistakenly. Similarly InPktsUnchecked
and InPktsOk share same counter and mode change was tracked
based on validate_check instead of validate_disabled.
This patch fixes those problems.
