The blkid_verify() function is designed to make sure the information in the cache corresponds with reality. If it does not, it will update the cache to match with reality, so it will do what you want. Using blkid_verify() will involve accessing the disk involved, but that's still better than the alternative of scanning all of the disks in the system.
