The commit be42660d0c13 ("s390/crash: use old os_info to create PT_LOAD headers")
introduced use of the old os_info into standalone dump kernel.
Before this change os_info_old_init() expected to be called only from
a regular kdump kernel although the function itself is able to work
in standalone dump kernels as well (because copy_oldmem_kernel() is able
to handle both use cases). Therefore, fix the expectation of os_info_old_init()
and enable it to be called from a standalone dump kernel.

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 reStructuredText 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.
