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.
