$cur_version is currently being tested twice with the first test
resulting in an unhelpful "$sphinx returned an error", not continuing to
the more helpful "$sphinx didn't return its version".
This patch removes the first test to return the more useful message.
Fixes: a8b380c379 ("scripts: sphinx-pre-install: only ask to activate valid venvs")
