tty: amiserial: fix broken TIOCMIWAIT
A change replacing interruptible_sleep_on() inadvertently broke the
TIOCMIWAIT implementation which now immediately returns -EIO (unless
there is a racing modem status update).
Replace the old hangup (and signal) detection with a check for the
TTY_IO_ERROR flag which is set on hangup.
Fixes: 591cee0a3563 ("tty/amiserial: avoid interruptible_sleep_on")
