wifi: nl80211: fix puncturing bitmap policy
This was meant to be a u32, and while applying the patch
I tried to use policy validation for it. However, not only
did I copy/paste it to u8 instead of u32, but also used
the policy range erroneously. Fix both of these issues.
Fixes: d7c1a9a0ed18 ("wifi: nl80211: validate and configure puncturing bitmap")
