Commit 256b152b (ath5k: don't enable
MSI, we cannot handle it yet) has removed msi support, but overlooked
the suspend/resume code. This patch completes msi removal.

I don't consider this patch copyrightable, and thus put it into the
public domain. The result is of course a base.c file dual-licensed under
3-clause-BSD and GPL.
