Fix a bug in syncache where the initial CWND for new incoming connections
was limited to one segment under the faulty assumption of a retransmit.
Due to this the opportunity to initialize the increased congestion window
according to RFC3390 was missed.

Support for RFC3465 introduced in r187289 uncovered the bug as the ACK
to SYN/ACK no longer caused snd_cwnd increase by MSS (actually, this
increase shouldn't happen as it's explicitly forbidden by RFC3390, but
it's another issue).  Snd_cwnd remains really small (1*MSS + 1) and this
causes really bad interaction with delayed acks on other side.

The variable name sc_rxmits is a bit misleading as it counts all transmits,
not just retransmits.
