tcp: fix cwnd rollover introduced by ABC
Changes for TCP Appropriate Byte Counting introduce a potential cwnd
rollover by not taking into account integer promotion on tcpwnd_size_t
during inequality comparisions
This fixes the issue by introducing a macro TCP_WND_INC which detects
the rollover correctly and now holds the tcpwnd_size_t at the maximum
value rather than not incrementing the window. This provides a slight
performance improvement by allowing full use of the tcpwnd_size_t number
space for the congestion window
