Jian J Wang 61a62fc258 MdeModulePkg/Core: fix an issue of potential NULL pointer access 
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=1286

This issue is introduced by bb685071c2.

The *MemorySpaceMap assigned with NULL (line 1710) value might be
accessed (line 1726/1730) without any sanity check. Although it won't
happen in practice because of line 1722, we still need to add check
against NULL to make static code analyzer happy.

1710  *MemorySpaceMap       = NULL;
....  ...
1722  if (DescriptorCount == *NumberOfDescriptors) {
....  ...
1726    Descriptor = *MemorySpaceMap;
....  ...
1730        BuildMemoryDescriptor (Descriptor, Entry);

Tests:
  Pass build and boot to shell.
