Mike Marciniszyn b8a7980405 IB/hfi1: Correct guard on eager buffer deallocation
commit 9292f8f9a2ac42eb320bced7153aa2e63d8cc13a upstream.

The code tests the dma address which legitimately can be 0.

The code should test the kernel logical address to avoid leaking eager
buffer allocations that happen to map to a dma address of 0.

README

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.
