tty: serial: samsung_tty: avoid dev_dbg deadlock

commit a05025d0ce72 ("tty: serial: samsung_tty: use standard
debugging macros") changed the debug prints to dev_dbg, which can
result in deadlocks:

s3c24xx_serial_set_termios can be called with the port lock, and then
calls dev_dbg, which needs the console mutex. At the same time,
s3c24xx_serial_console_write can be called with the console lock
(e.g., inside console_unlock), and needs the port lock.

To avoid this, move one dev_dbg call and just delete the other.
