dmverity: Suppress the realpath errors

If we use a non PARTUUID root parameter, we would always get a error
like below:
  realpath: /dev/disk/by-partuuid//dev/mmcblk0p2: No such file or directory

This seems pretty confusion and it also seems no need to emit this kind
of error when we are waiting for the root device. So suppress all the
realpath errors.
