platform/x86: intel_scu_ipc: Don't override scu in intel_scu_ipc_dev_simple_command()
Andy discovered this bug during patch review. The 'scu' argument to this
function shouldn't be overridden by the function itself. It doesn't make
any sense. Looking at the commit history, we see that commit
f57fa18583f5 ("platform/x86: intel_scu_ipc: Introduce new SCU IPC API")
removed the setting of the scu to ipcdev in other functions, but not
this one. That was an oversight. Remove this line so that we stop
overriding the scu instance that is used by this function.
