Leon Hwang b724a6418f bpf: Fix tr dereferencing
Fix 'tr' dereferencing bug when CONFIG_BPF_JIT is turned off.

When CONFIG_BPF_JIT is turned off, 'bpf_trampoline_get()' returns NULL,
which is same as the cases when CONFIG_BPF_JIT is turned on.

Closes: https://lore.kernel.org/r/202309131936.5Nc8eUD0-lkp@intel.com/

README

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.
