 ppp: Fix transmitting data

 The pppstart expected that a driver write would somehow magically
 process all data passed to the write function. Because ppp disables all
 buffering that originally has been in termios, that assumption is not
 true for all but polled drivers.

 With this patch, the pppstart now gets and processes the feedback that
 is returned from the driver via rtems_termios_dequeue_characters.

 Fixes #4493
