files: do not try writing to the status bar while not in curses mode 

Between an endwin() and a doupdate() there should be no calls of
statusline() or statusbar() -- these two functions may be called
only when in curses mode.

This fixes https://savannah.gnu.org/bugs/?58868.

Bug existed since version 4.3, commit 57390cff.
