add a self check for nil in cbg.Deferred. Also add an error check for Deferred.Raw = nil which causes an error on unmarshal

Goals
Handle two unusual cases for a cbg.Deferred value in the Marshalling process
Implementation
Resolution: add a self nil check in the Marshall method for *cbg.Deferred and write a cbor.Null
Resolution: this shouldn't happen. It means you forgot to serialize the deferred value into Raw. Moreover, currently it produces unpredictable behavior because Marshall will succeed (writing nothing), but then nothing is written to the buffer so if a Deferred is in a struct, the immediate proceeding field will likely have an unpredictable error, as it's data will be read into Raw on Unmarshal. Instead, return error on Marshal for this case.
