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.
