MercurySession::reconnect() nulls conn/shanConn (for 5 s per failed
retry) while other tasks keep sending through them: a NULL dereference,
not a catchable exception. Our Spotify sessions are dropped by the
server and reconnect every ~6 minutes, so this race is hit regularly;
likely behind the sporadic resets during long sessions/OTA.
Patch applies cleanly to the pinned 3010349; builds, boots, confirmed.
Drop it once the fix is in the pinned cspot commit.
