[PATCH 10/14] fast-export.c: Initialise variable to suppress msvc warning

The msvc compiler thinks that a variable could be used while
uninitialised and issues the following warning:

    ...\git\builtin\fast-export.c(466) : warning C4700: uninitialized \
        local variable 'commit' used

In order to suppress the warning, we simply initialise the
commit pointer variable to NULL.
