v5 - fix noacked
v4 - switch from Tx latency report to enable Tx count in txfree path for non-v3 format
v3 - add a missing check for mt7921
v2 - add a missing check for non-v3 format

@Deren, can you help to check if mt7921 can drop this  and calculate
tx_failed from txfree directly?

Hi Ryder,

mt7921 should follow txfree event as well. Please drop it in this patch
and I will post an new patch for mt7921 version.
