btrfs: qgroup: abort transaction on failure to add qgroup relation

When adding a qgroup relation, if we fail to add the relation item from
"dst" to "src", we attempt to delete the relation item from "src" to "dst"
that we added just before, however we ignore the deletion result and if we
failed to delete we leave an inconsistency in the quota root. So check the
result of the deletion and if it fails, abort the transaction to avoid
persisting an inconsistent state.
