user/node: Fix PPC64 patch to actually compile
The patch as committed was not finished. This finishes the patch.
Tested on G5 and Power9. No regressions on P9, 12 failures on G5 - which
is significantly better than the 3800 we had before.
Fixes: 5a785f870b ("user/node: Added fixes for pre-Power8 ppc64 CPUs")
