In x86_cpu_post_initfn(), the initialization of x86_ext_save_areas[] marks the unsupported xsave areas based on Host support.This step must be done before accel_cpu_instance_init(), otherwise, KVM's assertion on host xsave support would fail: qemu-system-x86_64: ../target/i386/kvm/kvm-cpu.c:149: kvm_cpu_xsave_init: Assertion `esa->size == eax' failed. (on AMD EPYC 7302 16-Core Processor) Move x86_ext_save_areas[] initialization to .instance_init and place it before accel_cpu_instance_init().
