rS355273: Move all ECN related flags from the flags to the flags2 field.

Summary

The first flags field in the tcpcb is nearly full.
In preparation of ECN related enhancements, moving
all these flags to the flags2 tcpcb field - so that
additional counters can also be defined in the same
cacheline later on, which are related to ECN.

This leaves a total of 5 unused bits in the flags field
