parentrev-parse: fix using "--default" with "--verify" (diff)

rev-parse --verify: do not output anything on error
Before this patch, when "git rev-parse --verify" was passed at least one good rev and then anything, it would output something for the good rev even if it would latter exit on error. With this patch, we only output something if everything is ok. Signed-off-by: Christian Couder <chriscool@tuxfamily.org> Signed-off-by: Junio C Hamano <gitster@pobox.com>
