z3fold_page_reclaim()'s retry mechanism is broken: on a second iteration it will have zhdr from the first one so that zhdr is no longer in line with struct page. That leads to crashes when the system is stressed. Fix that by moving zhdr assignment up. While at it, protect against using already freed handles by using own local slots structure in z3fold_page_reclaim().

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.
