[PULL 11/17] target/ppc: Zero second doubleword for VSX madd instructions |

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")
