Currently, add_kfunc_call() is only invoked once before the main verification loop. Therefore, the verifier could not find the bpf_kfunc_btf_tab of a new kfunc call which is not seen in user defined struct_ops operators but introduced in gen_prologue or gen_epilogue during do_misc_fixup(). Fix this by searching kfuncs in the patching instruction buffer and add them to prog->aux->kfunc_tab.

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.
