[PATCH AUTOSEL 5.18 57/93] scripts: sphinx-pre-install: fix venv version check logic

From: Mauro Carvalho Chehab <mchehab@kernel.org>

[ Upstream commit 7c2d45a347c7933cbe0efff14fe96adeb13fd761 ]

The logic which checks if the venv version is good enough
but was not activated is broken: it is checking against
the wrong val, making it to recommend to re-create a venv
every time. Fix it.
