Auto merge of #52106 - PramodBisht:issue/52049, r=oli-obk

Don't suggest `let` bindings if they don't help with borrows

@oli-obk I have added a condition to address #52049, right now, this is on WIP because I think code change is also required on `error_reporting.rs`. Plus I need to check if any test cases fail.
I will ping you again if everything passes
