[PATCH] tty: atmel_serial: update outdated reference to atmel_tasklet_func()

[Kexin Sun]

The modem-status comparison that used irq_status_prev was
moved from atmel_tasklet_func() into atmel_handle_status() in
commit 2c7af5ba65cf ("tty: serial: atmel: rework interrupt and
wakeup handling").  atmel_tasklet_func() itself was later split
into atmel_tasklet_rx_func() and atmel_tasklet_tx_func() in
commit 00e8e65870cc ("tty/serial: atmel: split tx and rx
paths").  Update the comment to reference
atmel_handle_status(), which now performs the comparison.
