Instead of rewriting error code returned by the kernel of prog load with libbpf-sepcific variants pass through the original error. There is now also no need to have a backup generic -LIBBPF_ERRNO__LOAD fallback error as bpf_prog_load() guarantees that errno will be properly set no matter what. Also drop a completely outdated and pretty useless BPF_PROG_TYPE_KPROBE guess logic. It's not necessary and neither it's helpful in modern BPF applications.

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.
