The m_num_mds here is actually the number for MDSs which are in up:active status, and it will be duplicated to m_num_active_mds, so remove it. Add possible_max_rank to the mdsmap struct and this will be the correctly possible largest rank boundary. Remove the special case for one mds in __mdsmap_get_random_mds(), because the validate mds rank may not always be 0.

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.
