The current definition of ftrace_regs_set_instruction_pointer() is not
correct. Obviously, this function is used to set instruction pointer but
not return value, so it should call instruction_pointer_set() instead of
regs_set_return_value().
There is no side effect by now because it is only used for kernel live-
patching which is not supported, so fix it to avoid failure when testing
livepatch in the future.

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.
