[libvirt] [PATCH] qemu: remove memset params array to zero in qemuDomainGetPercpuStats

[Gao feng]

the array params is allocated by VIR_ALLOC_N in cmdCPUStats.
it had been set to zero. No need to reset it to zero again,
and this reset here is incorrect too, nparams * ncpus is the
array length not the size of params array.
