libbpf ensures that BPF program references set in map->st_ops->progs[i] during open phase are always valid STRUCT_OPS programs. This is done in bpf_object__collect_st_ops_relos(). So there is no need to double-check that in bpf_map__init_kern_struct_ops(). Simplify the code by removing unnecessary check. Also, we avoid using local prog variable to keep code similar to the upcoming fix, which adds similar logic in another part of bpf_map__init_kern_struct_ops().

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 reStructuredText 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.
