Geliang Tang b9a395f0f7 bpf, btf: Fix return value of register_btf_id_dtor_kfuncs
The same as __register_btf_kfunc_id_set(), to let the modules with
stripped btf section loaded, this patch changes the return value of
register_btf_id_dtor_kfuncs() too from -ENOENT to 0 when btf is NULL.

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
