mlx4_en: Fix BQL reset TX queue call point
Fix issue in Mellanox driver related to BQL. netdev_tx_reset_queue
was not being called in certain situations where the device was
being start and stopped. Moved netdev_tx_reset_queue from the reset
device path to mlx4_en_free_tx_buf which is where the rings are
cleaned in a reset (specifically from device being stopped).
