Fix Ceph device parsing to use devices line

The "block device" line in ceph-volume output shows LVM paths like
ceph-xxx/osd-block-xxx, not physical device names. Changed to parse
the "devices" line which contains the actual physical device path
like /dev/sda.

Also reset current_osd after match to avoid duplicate matches.

Fixes: #17
