This allocates the infrastructure to make a new RxRPC call and assigns
call and connection numbers. The call will be made on the UDP port that
allows the kernel to encrypt directly to the packet buffers, thereby
saving a copy. The value may not be less than -1.
+ notify_rx is a pointer to a function to be called when events such as
+ incoming data packets or remote aborts happen.
+
+ upgrade should be set to true if a client operation should request that
+ the server upgrade the service to a better one. The resultant service ID
+ is returned by rxrpc_kernel_recv_data().
+
If this function is successful, an opaque reference to the RxRPC call is
returned. The caller now holds a reference on this and it must be
properly ended.

This is used to receive data from either the reply part of a client call
or the request part of a service call. buf and size specify how much
If a remote ABORT is detected, the abort code received will be stored in
*_abort and ECONNABORTED will be returned.
+ The service ID that the call ended up with is returned into *_service.
+ This can be used to see if a call got a service upgrade.
