Remove duplicated BTF parsing logic when it comes to subprog call check. Instead, use (potentially cached) results of btf_prepare_func_args() to abstract away expectations of each subprog argument in generic terms (e.g., "this is pointer to context", or "this is a pointer to memory of size X"), and then use those simple high-level argument type expectations to validate actual register states to check if they match expectations.

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.
