John Ferlan 148cfcf051 qemu: Pass / fill niothreads for qemuMonitorGetIOThreads
Let's pass along / fill @niothreads rather than trying to make dual
use as a return value and thread count.

This resolves a Coverity issue detected in qemuDomainGetIOThreadsMon
where if qemuDomainObjExitMonitor failed, then a -1 was returned and
overwrite @niothreads causing a memory leak.
