Bob Pearson b18c7da63f RDMA/rxe: Fix memory leak in error path code
In rxe_mr_init_user() at the third error the driver fails to free the
memory at mr->map. This patch adds code to do that.  This error only
occurs if page_address() fails to return a non zero address which should
never happen for 64 bit architectures.

Fixes: 8700e3e7c4 ("Soft RoCE driver")

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.
