iwlwifi: allow rate-limited error messages

Browse source

Sometimes we might want to have an error message for something
related to TX/RX, but if that somehow happens frequently it'll
overwhelm the logs. Add IWL_ERR_LIMIT() to alleviate that by
rate-limiting those messages.

To do this, rework __iwl_err() a bit to have a mode argument
instead of passing yet another (bool) argument to it.
