sctp: Fix broken RTO-doubling for data retransmits
Commit faee47cdbfe8d74a1573c2f81ea6dbb08d735be6
(sctp: Fix the RTO-doubling on idle-link heartbeats)
broke the RTO doubling for data retransmits. If the
heartbeat was sent before the data T3-rtx time, the
the RTO will not double upon the T3-rtx expiration.
Distingish between the operations by passing an argument
to the function.
Additionally, Wei Youngjun pointed out that our treatment
of requested HEARTBEATS and timer HEARTBEATS is the same
wrt resetting congestion window. That needs to be separated,
since user requested HEARTBEATS should not treat the link
as idle.
