afs: Use the fs operation ops to handle FetchData completion
Use the 'success' and 'aborted' afs_operations_ops methods and add a 'failed' method to handle the completion of an AFS.FetchData, AFS.FetchData64 or YFS.FetchData64 RPC operation rather than directly calling the done func pointed to by the afs_read struct from the call delivery handler. This means the done function will be called back on error also, not just on successful completion. This allows motion towards asynchronous data reception on data fetch calls and allows any error to be handed off to the fscache read helper in the same place as a successful completion.
