====================
mptcp: new reviewer and prevent a warning

Patch 1 adds MPTCP long time contributor -- Geliang Tang -- as a new
reviewer for the project. Thanks!

Patch 2 prevents a warning when TCP Diag is used to close internal MPTCP
listener subflows. This is a correction for a patch introduced in v6.4
which was fixing an issue from v5.17.
