If that is your rules file, it is invalid; did you run 'udevtest' on
the /dev entry to see what happens?
udevtest /dev/ttyS0

You are missing the comma ',' to separate RUN+= from SYMLINK+= and the
"last_rule" will prevent your second 'KERNEL=="ttyS0"' from being
processed.  From what I can see, 'setserial' will not be run because
udev cannot make sense of the line.
