TransactionClient `gc` function often enters error loop during CleanupLocks

[jmhrpr]

I have a program that runs periodically which makes a single call to the TransactionClient gc function. Around half of the time it enters some loop which prints thousands of these logs and eventually OOMs. It is checking many ranges/regions for the the same key. It is a different key each time it enters the loop. They are INFO logs originating from client-rust-da362376b56921db/1fa846b/src/request/plan.rs:686.
