Description of problem

Fix commit: a90db158 When using the Record/replay feature on ppc emulation (qemu-system-ppc binary), an error occurred during loading:

qemu-system-ppc: Missing section footer for cpu
qemu-system-ppc: Error -22 while loading VM state
qemu-system-ppc: Could not load snapshot for icount replay

I found a typo that led to this error
