drbd: fix spurious alert level printk
When accessing out meta data area on disk, we double check the plausibility of the requested sector offsets, and are very noisy about it if they look suspicious. During initial read of our "superblock", for "external" meta data, this triggered because the range estimate returned by drbd_md_last_sector() was still wrong.
