As per a comments in [1] by Greg Kroah-Hartman, the ndev_* macros should
be cleaned up. This makes it more clear what's actually going on when
reading the code.

Hi,
I had copied some poor code style from the NTB drivers into an unrelated
driver. Upon review of my new code, I learned it was not a good idea
to sweep dirty things under the rug^W macro. See [1], where Gregg k-h
suggested I fix the problem at the source.
Thus, please merge the following two patches to improve the style of
the NTB drivers.
Thanks,
Logan
