Switching to libbpf 1.0 API broke test_lpm_map and test_lru_map as error
reporting changed. Instead of setting errno and returning -1 bpf calls
now return -Exxx directly.
Drop errno checks and look at return code directly.
Fixes: b858ba8c52 ("selftests/bpf: Use libbpf 1.0 API mode instead of RLIMIT_MEMLOCK")

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.
