diffcore-rename.c: avoid set-but-not-used warning

Since 9d8a5a5 (diffcore-rename: refactor "too many candidates" logic, 2011-01-06), diffcore_rename() initializes num_src but does not use it anymore. "-Wunused-but-set-variable" in gcc-4.6 complains about this. Signed-off-by: Jim Meyering <[email protected]> Signed-off-by: Junio C Hamano <[email protected]>
