Prog arrays don't have 'owner_prog_type' and 'owner_jited'
fields in their fdinfo when they are created. Those fields
are set and reported when first program is checked for
compatibility by bpf_prog_array_compatible().
This means that bpftool cannot expect the fields to always
be there. Currently trying to show maps on a system with
an un-owned prog array leads to a crash:
$ bpftool map show
389: prog_array name tail_call_map flags 0x0
Error: key 'owner_prog_type' not found in fdinfo
Error: key 'owner_jited' not found in fdinfo
key 4B value 4B max_entries 4 memlock 4096B
Segmentation fault (core dumped)
We pass a NULL pointer to atoi().
Remove the assumption that fdinfo keys are always present.
Add missing validations and remove the p_err() calls which
may lead to broken JSON output as caller will not propagate
the failure.

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.
