octeontx2-pf: mcs: Clear stats before freeing resource

Browse Source 
[ Upstream commit 815debbbf7b52026462c37eea3be70d6377a7a9a ]

When freeing MCS hardware resources like SecY, SC and
SA the corresponding stats needs to be cleared. Otherwise
previous stats are shown in newly created macsec interfaces.
