uart: esp32: fix baudrate return value

Browse source 
HAL call function used to retrieve the configured baudrate
returns the real calculated value, which might not be exactly as
the configured. For baudrate of 115200, HAL api
returns 115201, which then causes uart_basic_api test
to fail. Instead of returning the calculated baudrate value,
returns the configured one.
