From: Geliang Tang <tanggeliang@kylinos.cn>

This patch simplifies MPTCP's TCP_MAXSEG getsockopt handling by moving it
to the common case where other TCP options are processed. Previously it
was handled separately after the main switch statement.

This improves code consistency without altering behavior.
