net: dsa: sja1105: Fix assigned yet unused return code rc
The return code variable rc is being set to return error values in two places in sja1105_mdiobus_base_tx_register and yet it is not being returned, the function always returns 0 instead. Fix this by replacing the return 0 with the return code rc.
