[PATCH 30/97] target/ppc: Fix lxvw4x, lxvh8x and lxvb16x

[Michael Roth]

From: Anton Blanchard <address@hidden>

During the conversion these instructions were incorrectly treated as
stores. We need to use set_cpu_vsr* and not get_cpu_vsr*.

Fixes: 8b3b2d75c7c0 ("introduce get_cpu_vsr{l,h}() and set_cpu_vsr{l,h}() 
helpers for VSR register access")
