Viktor Mihajlovski a0a71efde0 fdasd: Fix endless menu loop on EOF ...

Hitting CTRL-D anywhere will cause fdasd to go into an endless loop
displaying the main menu over and over again. Killing fdasd (e.g.
via CTR-C) is the only way out.
The issue is that read_line() is just ignoring the resulting EOF
condition on stdin. Subsequent invocations of read_line() will return
immediately and thus cause the loop. A simple fix is to reset stdin
after EOF. A caller of read_line() will see the same behavior as for
EOL with no input.
