btrfs: Don't panic when we can't find a root key [ Upstream commit 7ac1e464c4d473b517bb784f30d40da1f842482e ] When we failed to find a root key in btrfs_update_root(), we just panic. That's definitely not cool, fix it by outputting an unique error message, aborting current transaction and return -EUCLEAN. This should not normally happen as the root has been used by the callers in some way.
