Maor Gottlieb 371979069a RDMA/cma: Use correct address when leaving multicast group
commit d9e410ebbe upstream.

In RoCE we should use cma_iboe_set_mgid() and not cma_set_mgid to generate
the mgid, otherwise we will generate an IGMP for an incorrect address.

Fixes: b5de0c60cc ("RDMA/cma: Fix use after free race in roce multicast join")

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.
