Tetsuo Handa ae01e52da2 serial: drop debugging WARN_ON_ONCE() from uart_write() ...

syzbot is reporting lockdep warning upon

  int disc = 7;
  ioctl(open("/dev/ttyS3", O_RDONLY), TIOCSETD, &disc);

sequence. Do like what commit 5f1149d2f4 ("serial: drop debugging
WARN_ON_ONCE() from uart_put_char()") does.
