amd-xgbe: handle the corner-case during tx completion
The existing implementation uses software logic to accumulate tx
completions until the specified time (1ms) is met and then poll them.
However, there exists a tiny gap which leads to a race between
resetting and checking the tx_activate flag. Due to this the tx
completions are not reported to upper layer and tx queue timeout
kicks-in restarting the device.
To address this, introduce a tx cleanup mechanism as part of the
periodic maintenance process.
