====================
mptcp: fix warn on bad status

Two somewhat related fixes addressing different issues found by
syzkaller, and producing the exact same splat: a WARNING in
subflow_data_ready().

- Patch 1: fallback earlier on simultaneous connections to avoid a
  warning. A fix for v5.19.

- Patch 2: ensure context reset on disconnect, also to avoid a similar
  warning. A fix for v6.2.
