n_tty: Fix EOF push index when termios changes
Commit 40d5e0905a03601d40cd4e46b8690093c2355d03,
'n_tty: Fix EOF push handling' introduced a subtle state
change error wrt EOF push handling when the termios is
changed from non-canonical to canonical mode.
Reset line_start to the current read_tail index, not 0.
