tty/serial: atmel: reschedule TX after RX was started

commit d2ace81bf902a9f11d52e59e5d232d2255a0e353 upstream.

When half-duplex RS485 communication is used, after RX is started, TX
tasklet still needs to be  scheduled tasklet. This avoids console freezing
when more data is to be transmitted, if the serial communication is not
closed.
