octeontx2-pf: mcs: Clear stats before freeing resource

BugLink: https://bugs.launchpad.net/bugs/2028580

[ Upstream commit 815debb ]

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.
