23e54bb0 introduced multiple hypervisors support for cpu and memory
overcommit. Here the HypervisorGuru base which determines the min, max
range for the memory for all hypervisors computes the minCpu using the
MemoryOverCommit ratio and minMemory using the CpuOverCommit ratio.
Minor typo/logic issue but massive damage across all HV if enabled ;)
