rGbb9525f30214: TCP RACK: fix TCP fast open

Summary

Do not jump to a place in the code, which requires several variables
to be set (segsize, minseg, idle, len, sb_offset), which is not true.
To avoid using these variables, start the HPTS timer explicitly.
This fix only applies to the client side using TCP fast open.
