btrfs: print the actual offset in btrfs_root_name
[ Upstream commit 71008734d27f2276fcef23a5e546d358430f2d52 ]
We're supposed to print the root_key.offset in btrfs_root_name in the
case of a reloc root, not the objectid. Fix this helper to take the key
so we have access to the offset when we need it.
Fixes: 457f1864b569 ("btrfs: pretty print leaked root name")
