sw:drv: [bugfix] replace flip_buffer_push() with schedule_flip()

a9c3f68 tty: Fix low_latency BUG Use directly the tty_schedule_flip(), when running on older kernel the tty_flip_buffer_push() may try to run flush_to_ldisc() in interrupt context. Signed-off-by: Federico Vaga <federico.vaga@vaga.pv.it>
