From: Víctor Colombo <victor.colombo@eldorado.org.br>

In 205eb5a89e we updated most VSX instructions to zero the
second doubleword, as is requested by PowerISA since v3.1.
However, VSX_MADD helper was left behind unchanged, while it
is also affected and should be fixed as well.

This patch applies the fix for MADD instructions.

Fixes: 205eb5a89e ("target/ppc: Change VSX instructions behavior to fill with zeros")
