BUG/MEDIUM: haterm: Subscribe for receives until request was fully drained

When draining the request, if some data were received, no subscribe for
receives was performed to get the remaining. However, because request data
are just ignored, we must always subscribe until it was fully
drained. Otherwise, haterm will never be woken up to drain more data.
