net: usb: r8152: fix transmit queue timeout

Browse source

When the TX queue length reaches the threshold, the netdev watchdog
immediately detects a TX queue timeout.

This patch updates the trans_start timestamp of the transmit queue
on every asynchronous USB URB submission along the transmit path,
ensuring that the network watchdog accurately reflects ongoing
transmission activity.
