The 'status' field of send_socket_request is always either STATUS_PENDING or STATUS_DEVICE_NOT_READY, and the 'total' field is always zero.
Replace the 'status' field with 'force_async' boolean field, and get rid of the 'total' field entirely.
Also, clean up the send_socket handler code a bit.

Notes: v1 -> v2: - adjust patch for new field "data_size" in send_socket_request v2 -> v3: no changes v3 -> v4: no changes v4 -> v5: no changes v5 -> v6: - centralise status code computation in one place, even for bind errno translation
