[PATCH 08/14] submodule.c: Initialise variables to suppress msvc warnings

The msvc compiler thinks that two variables could be used
while uninitialised and issues the following warnings:

    ...\git\submodule.c(147) : warning C4700: uninitialized local \
        variable 'left' used
    ...\git\submodule.c(147) : warning C4700: uninitialized local \
        variable 'right' used

In order to suppress the warnings, we simply initialise the
pointer variables to NULL.
