btrfs-progs: fix uninitialized copy of btrfs_fs_devices list 

Noticed that at print_one_uuid() some of the members of btrfs_fs_devices
contained some junk values. It took a while to dig this further, and found
that we make a local copy of the btrfs_fs_devices list at
search_umounted_fs_uuids() and wasn't initialized properly.

Fixed using using calloc instead of malloc.
