tcp: move tp->chrono_type next tp->chrono_stat[]
chrono_type is currently in tcp_sock_read_txrx group, which
is supposed to hold read-mostly fields.
But chrono_type is mostly written in tx path, it should
be moved to tcp_sock_write_tx group, close to other
chrono fields (chrono_stat[], chrono_start).
Note this adds holes, but data locality is far more important.
Use a full u8 for the time being, compiler can generate
more efficient code.
