[L0] Fix DeviceInfo global mem free to report global if MemCount==0

nrspruit · nrspruit · commit c9132985bb56 · 2024-03-29T13:56:53.000-07:00
- If there are no memory modules from zesDeviceEnumMemoryModules, then
  don't use the free memory value to report global mem free, but instead
return the GlobalMemSize.
