Subject: [PATCH] vddk: Include VDDK major library version in --dump-plugin
output
Although it doesn't seem to be possible to get the precise VDDK
version, With a relatively simple change we can at least return the
VDDK major version. Currently this can be 5, 6 or 7.
(cherry picked from commit 8700649d147948897f3b97810a1dff37924bdd6e)

Subject: [PATCH] vddk: Only print vddk_library_version when we managed to load
the library
Because --dump-plugin calls load_library (false) it won't fail if we
didn't manage to load the library. This results in library_version
being 0, which we printed incorrectly.
Resolve this problem by not printing the vddk_library_version entry in
this case.
Fixes: commit 8700649d147948897f3b97810a1dff37924bdd6e
(cherry picked from commit a3fba12c3e9c2113009f556360ae0bd04c45f6bb)
