MdeModulePkg/DxeCore: Avoid accessing non-owned memory
The patch fixes two kinds of bugs in DxeCore that accesses memory
which might be freed or owned by other modules.
The two bugs don't cause functionality issue.
1. CoreValidateHandle() checks whether the handle is valid by
validating its signature. The proper way is to check whether
the handle is in the handle database.
2. CoreDisconnectControllersUsingProtocolInterface() and
CoreOpenProtocol() de-reference Link pointer which is
already freed. The proper way is to not de-reference the pointer.
