server: Replace redundant send_socket status fields with force_async boolean field. 

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.
