Auto merge of rust-lang#6354 - Daniel-B-Smith:refcell_ref_await, r=flip1995

Downgrade the await holding lints from correctness

We found a false positive in these lints (see rust-lang/rust-clippy#6353 for more details). As a short-term mitigation, this downgrades the lints from correctness to limit the noise.

changelog: downgrade AWAIT_HOLDING_REFCELL_REF and AWAIT_HOLDING_LOCK to pedantic. From rustup earlier, where I forgot the changlog: deprecate [`panic_params`] (uplifted)
