[PATCH] netfilter: nf_tables: Fix an Oops in nf_tables_updobj() error handling

[Dan Carpenter <dan.carpenter@oracle.com>]

The "newobj" is an error pointer so we can't pass it to kfree().  It
doesn't need to be freed so we can remove that and I also renamed the
error label.

Fixes: d62d0ba97b58 ("netfilter: nf_tables: Introduce stateful object update operation")
