[MPlayer-dev-eng] No need to enable getch2 more then once

[Andreas Hess]

Hello!

When using mplayer with -gui my terminal is always broken after
finishing a video. It doesn't display new entered characters any
longer.
I think the problem is, that getch2 will be enabled a second time
after finishing the video. The same problem should occur when
playing multiple files.
The following fixes this problem (at least for me):
