[libcamera-devel] [PATCH] test: buffer_import: Initialize media_ and video_

When the vivid module used to test buffer importing is not loaded, the
test correctly bails out, but during the clean up procedure tries to
access the video_ fields, which, if not correctly initialized to
nullptr, contains random values and accessing it cause a segfault.

Fix this by initializing video_ field to nullptr to make sure it is
properly handled in cleanup().
