input_default_getkeycode_from_index() returns the scancode at kt_entry.scancode

In time:

-           kt_entry.scancode = &scancode;
+         kt_entry.scancode = (char *)&scancode;

Otherwise, a warning would be produced ;)

Still dies, but in input_set_keycode() instead...

*ping*?  Still broken in a linux-next pull I did about an hour ago.  The
