Commit24dea04767("bpf, x32: remove ld_abs/ld_ind") removed the 4 /* Extra space for skb_copy_bits buffer */ from _STACK_SIZE, but it didn't fix the concerned code in emit_prologue and emit_epilogue, and this error will bring very strange kernel runtime errors. This patch fixes it.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
