David Disseldorp 63ce3c384d scsi: target: Fix truncated PR-in ReadKeys response
SPC5r17 states that the contents of the ADDITIONAL LENGTH field are not
altered based on the allocation length, so always calculate and pack the
full key list length even if the list itself is truncated.

According to Maged:

  Yes it fixes the "Storage Spaces Persistent Reservation" test in the
  Windows 2016 Server Failover Cluster validation suites when having
  many connections that result in more than 8 registrations. I tested
  your patch on 4.17 with iblock.

This behaviour can be tested using the libiscsi PrinReadKeys.Truncate test.

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.
