From: Johannes Berg <johannes.berg@xxxxxxxxx> As documented in the comment, this queue sync was here to ensure that an async IWL_MVM_RXQ_NSSN_SYNC queue sync won't race with setting up a new BA session with the same BAID. However, we no longer do IWL_MVM_RXQ_NSSN_SYNC queue sync, so we can remove this as well.
