Re: [PATCH] netfilter: x_tables: handle xt_register_template() returning an error value

Commit fdacd57c79b7 ("netfilter: x_tables: never register tables by
default") introduces the function xt_register_template(), and in one case,
a call to that function was missing the error-case handling.

Handle when xt_register_template() returns an error value.

This was identified with the clang-analyzer's Dead-Store analysis.

This needs to go to nf-next.
