Star Zeng 69a8a9ee20 MdePkg DxeServicesLib: Handle potential NULL FvHandle
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=514

The FvHandle input to InternalGetSectionFromFv() may be NULL,
then ASSERT will appear. It is because the LoadedImage->DeviceHandle
returned from InternalImageHandleToFvHandle() may be NULL.
For example for DxeCore, there is LoadedImage protocol installed
for it, but the LoadedImage->DeviceHandle could not be initialized
before the FV2 (contain DxeCore) protocol is installed.

This patch is to update InternalGetSectionFromFv() to return
EFI_NOT_FOUND directly for NULL FvHandle.
