btrfs: handle invalid root reference found in btrfs_init_root_free_objectid()

Browse source

The btrfs_init_root_free_objectid() looks up a root by a key, allowing
to do an inexact search when key->offset is -1.  It's never expected to
find such item, as it would break the allowed range of a root id.
