live: validate checksum only once if image is already in cache
if image already exists in the cache, skip a second checksum validation. log shows duplicated entries: Verifying checksum for example.img, please wait... Checksum is OK for example.img Verifying checksum for example.img, please wait... Checksum is OK for example.img because tip_check_csum() is called twice in this case.
