really reset walker with git_revwalk_reset
really reset walker with git_revwalk_reset

From the description  of git_revwalk_reset in revwalk.h the function should
clear all pushed and hidden commits, and leave the walker in a blank state (just like at creation).
Apparently everything gets reseted appart of pushed commits (walk->one and walk->twos)

This fix should reset the walker properly.
