feedback: when not in curses mode, just skip displaying any message

Calling die() could trigger another call of emergency_save(), which
could fail and cause another call to statusline(), which would call
die() again...  Spiralling until stack space runs out.

This fixes https://savannah.gnu.org/bugs/?60853.

Bug existed since version 5.1, commit 7942dab0.

Original report was in https://bugzilla.redhat.com/1976410.
