According to the new initial flow of this new chip, the tx/rx would be enabled
in rtl_hw_start_8168g_2 function. And this function is run before
rtl_set_rx_tx_desc_registers. It would be a problem, so I move
rtl_set_rx_tx_desc_registers to make sure that the descriptor address would be
set before the tx/rx is enabled. It has no influence for the previous chips, and
I think the following new chips would base on the new flow.

Best Regards,
Hayes
