vfio: platform: Do not pass return buffer to ACPI _RST method
[ Upstream commit e67e070632a665c932d534b8b800477bb3111449 ]
The ACPI _RST method has no return value, there's no need to pass a return
buffer to acpi_evaluate_object().
Fixes: d30daa33ec1d ("vfio: platform: call _RST method when using ACPI")
