rtase: Reset TX subqueue when clearing TX ring

Browse Source 
rtase_tx_clear() clears the TX ring and resets the ring indexes.
However, the TX queue state and BQL accounting are not reset at
the same time.

This may leave __QUEUE_STATE_STACK_XOFF asserted after
rtase_sw_reset(), preventing new TX packets from being scheduled.

Reset the TX subqueue when clearing the TX ring so the TX queue
state and BQL accounting are restored together.
