…ce, r=cjgillot Revert "Don't hold the active queries lock while calling `make_query`" This reverts commit fd3d2d4.

Reverts rust-lang#112333 r? `@cjgillot` cc `@Zoxc` I only commented this on [Zulip](https://rust-lang.zulipchat.com/#narrow/stream/131828-t-compiler/topic/.60try_print_query_stack.60.20has.20.60ImplicitCtx.60.20during.20.60EarlyPass.60/near/363926180). I should've left a comment on the PR as well. My bad.

This moves the call to
