i386/cpu: Move x86_ext_save_areas[] initialization to .instance_init
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().
Fixes: commit 5f158abef44c ("target/i386: move accel_cpu_instance_init to .instance_init")
