[PATCH v5] commit-graph: remove a duplicate assignment

[Alex Henrie <alexhenrie24@gmail.com>]

Leave the variable 'g' uninitialized before it is set just before its
first use in front of a loop, which is a much more appropriate place to
indicate what it is used for.

Also initialize the variable 'num_commits' just before the loop instead
of at the beginning of the function for the same reason.
