bpf: Add DEBUG_INFO_BTF checks for __register_bpf_struct_ops
This patch set avoids module loading failure when the module
trying to register a struct_ops and the module has its btf section
stripped. This will then work similarly as module kfunc registration in
commit 3de4d22cc9ac ("bpf, btf: Warn but return no error for NULL btf from __register_btf_kfunc_id_set()")
v5:
- drop CONFIG_MODULE_ALLOW_BTF_MISMATCH check as Martin suggested.
v4:
- add a new patch to fix error checks for btf_get_module_btf.
- rename the helper to check_btf_kconfigs.
v3:
- fix this build error:
kernel/bpf/btf.c:7750:11: error: incomplete definition of type 'struct module'
Reported-by: kernel test robot <lkp@intel.com>
Closes: https://lore.kernel.org/oe-kbuild-all/202402040934.Fph0XeEo-lkp@intel.com/
v2:
- add register_check_missing_btf helper as Jiri suggested.

============
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.
