[PULL 02/11] ACPI: Avoid infinite recursion when dump-vmstate

["Dr. David Alan Gilbert (git)" <dgilbert@redhat.com>]

From: Peng Liang <liangpeng10@huawei.com>

There is a field with vmstate_ghes_state as vmsd in vmstate_ghes_state,
which will lead to infinite recursion in dump_vmstate_vmsd.

Fixes: a08a64627b ("ACPI: Record the Generic Error Status Block address")
