Most of the samples were converted to use the new BTF-defined MAP as they moved to libbpf, but some of the samples were missing. Instead of using the previous BPF MAP definition, this commit refactors xdp_monitor and xdp_sample_pkts_kern MAP definition with the new BTF-defined MAP format. Also, this commit removes the max_entries attribute at PERF_EVENT_ARRAY map type. The libbpf's bpf_object__create_map() will automatically set max_entries to the maximum configured number of CPUs on the host. Signed-off-by: Daniel T.

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.
