[PATCH v3 2/5] tree-walk.c: remove name_compare() function

Remove the duplicate name_compare() function and use the one provided by
read-cache.c.

Notes:
    There is one small difference between the old function and the new one.
    The old one returned -N and +N whereas the new one returns -1 and +1.
    However, there is no place where the magnitude was needed, so this
    change will not alter its behavior.
