From the 2017 Ranked Rewards Eligibility Page:
There are a few ways to miss out on this season’s rewards:
- Players with bans or chat restrictions active when the season ends are ineligible for this year’s rewards.
- Players issued a ban of seven days or more from 8/22/2017 are ineligible for this year’s rewards.
- Players banned for boosting during the 2017 season remain ineligible for rewards.
- Players who experience fraud-related or erroneous bans will still be eligible.
So, you should be fine on the ranked rewards, as long as you play out the chat restriction and don't progress up to another one or a ban. As far as the Honor unlocking:
What do you mean by lock my Honor level and rewards?
You'll see a lock on your Honor level in your profile. This means you aren't making any progress to the next level, and you won't receive any rewards. Unlock your Honor level by putting clean games in. You’ll get a notification when you’ve unlocked your Honor level.
