tty: serial: Samsung: Fix return value
Return the value returned by the failing function instead of -1 (which does not convey the right error information). Fixes the following smatch warning: drivers/tty/serial/samsung.c:1687 s3c24xx_serial_modinit() info: why not propagate 'ret' from uart_register_driver() instead of -1?
