osd_disk_activate: resolve device symlink

When using OSD_DEVICE variable with /dev/disk/by-[id|path] then the
partition name is different for the ceph data partition. There's an
additional '-part' prefix before the partition number.
Instead of managing this prefix and considering that files located in
the /dev/disk/by-[id|path] directories are symlinks then we can resolve
the symlink to get the actual device /dev/xxxx.

Closes: ceph#1480
