qemuBuildNumaCommandLine: Fix @masterInitiator check

Browse Source 
A few commits ago, in aeecbc87b7, I've implemented command line
generation for ACPI HMAT. For this, we need to know if at least
one guest NUMA node has vCPUs. This is tracked in
@masterInitiator variable, which is initialized to -1, then we
iterate through guest NUMA nodes and break the loop if we find a
node with a vCPU. After the loop, if masterInitiator is still
negative then no NUMA node has a vCPU and we error out. But this
exact check was missing comparison for negativeness.
