    octeontx2-pf: mcs: Clear stats before freeing resource
    
    [ 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.
