Currently, when building sphinx documentation, the build will only succeed if being run from the build system, because the conf.py script expects DPDK_VERSION environment variable to be set, and crashes if it is not. However, there are certain external tools (such as sphinx documentation preview extensions for certain IDE's) that use live preview and thus rely on running their own sphinx commands. In these cases, it is useful to permit building sphinx documentation without specifying the DPDK_VERSION environment variable. The version string is the only thing preventing manual sphinx build commands from working. Fix the conf.py to use "None" as a version string in cases when DPDK_VERSION environment variable is not set.
