sctp: Correctly start rtx timer on new packet transmissions.

Browse Source 
[ Upstream commit 6574df9a89 ]

Commit 62aeaff5cc
(sctp: Start T3-RTX timer when fast retransmitting lowest TSN)
introduced a regression where it was possible to forcibly
restart the sctp retransmit timer at the transmission of any
new chunk.  This resulted in much longer timeout times and
sometimes hung sctp connections.
