cpu: Fix VMSTATE_CPU() semantics
Commit
1a1562f5ea3da17d45d3829e35b5f49da9ec2db5 prepared a VMSTATE_CPU()
macro for device-style VMStateDescription registration, but missed to
adapt cpu_exec_init(), so that the "cpu_common" VMStateDescription was
still registered for AlphaCPU (
fe31e7374299c0c6172ce618b29bf2fecbd881c7)
and OpenRISCCPU (
da69721460e652072b6a3dd52b7693da21ffe237). Fix this.
