Andrew McCreight 7157f25222 Bug 1655536, part 1 - Drop the return value from MemoryReportRequestClient::FinishCallback. r=froydnj
The next patch converts the memory reporting architecture to use the "returns"
feature of IPDL, and mozilla::ipc::RejectCallback does not have a return
type, so this patch removes the return value.

FinishReportingCallback::Callback() needs to remain an XPCOM method
that returns NS_OK because it is called from JS during testing.
