[PATCH] Fix for trivial fix for 2.6.11 raid6 compilation on ppc w/ Altivec

Here's a patch that will work for both PPC and PPC64. The proper way to
fix this in mainline is to merge -mm's cpu_has_feature patch, but for
the stable 2.6.11-series, this much less intrusive (i.e. just the pure
bugfix, not the cleanup part).
