qcacmn: Enable update of per-peer statistics in MSDU Tx completions

Update of per-peer statistics was disabled from per-MSDU indications
as they are now updated from per-PPDU indications. However, the data from
per-PPDU indications is incorrect for some fields. Re-enable update of
statistics for per-MSDU completions till this issue is fixed in FW
