ArmPkg/BdsLib: Fixed ShutdownUefiBootServices() in case the first gBS->GetMemoryMap() was successful 

If the first call of gBS->GetMemoryMap() succeeded (could happen if the Memory Map
has changed between the two gBS->GetMemoryMap() calls) in the loop block then
gBS->ExitBootServices() was never called.
