qemu: monitor: clear cpu props properly in CPUInfoClear

Stay true to the name of the function and clear the pointer
after freeing it.

This also silences a bogus Coverity report about a double
free in qemuMonitorGetCPUInfo where qemuMonitorCPUInfoClear
is called right after allocating a new qemuMonitorCPUInfo
to fill out the non-zero defaults.
