[PATCH 18/23] qemuProcessSetupHotpluggableVcpus: Use automatic memory freeing

[Peter Krempa]

'bootHotplug' can be auto-freed when terminating the function and moving
the declaration of 'vcpuprops' to the loop which uses it along with
automatic freeing allows us to simplify cleanup in certain cases.
