In HAST we use two sockets - one for only sending the data and one for

only receiving the data. In r220271 the unused directions were
disabled using shutdown(2).

Unfortunately, this broke automatic receive buffer sizing, which
currently works only for connections in ETASBLISHED state. It was a
root cause of the issue reported by users, when connection between
primary and secondary could get stuck.

Disable the code introduced in r220271 until the issue with automatic
buffer sizing is not resolved.
