[PATCH v2] serial: samsung: Fixed wrong comparison for baudclk_rate

[Kyoungil Kim]

port->baudclk_rate should be compared to the rate of port->baudclk,
because port->baudclk_rate was assigned as the rate of port->baudclk previously.
So to check that the current baudclk rate is same as previous rate,
the target of comparison sholud be the rate of port->baudclk.
