rGf42518ff1250: tcp: for LRD move sysctl from tcp.do_lrd tp tcp.sack.lrd, remove sockopt

Summary

Lost Retransmission Detection for the base stack:

Moving the sysctl control to the tcp.sack branch, as LRD only works in conjunction with SACK loss recovery - and update the tcp.4 man page accordingly.

Also, remove the sockopt to programmatically control LRD per session, as there is no known use of that functionality
