The DEAD_RELOC_TREE flag is in place in order to avoid a use after free in init_reloc_root, tracking the presence of reloc_root. However adding the explicit tree references in previous patches makes the use after free impossible because at this point we no longer have a reloc_control set on the fs_info and thus cannot enter the function. So move this to be coupled with clearing the root->reloc_root so we're consistent with all other operations of the reloc root.

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.
