mac80211: restrict advertised HW scan rates
Advertise only user-requested bitrates in a HW scan.
Note that the hw_scan API doesn't currently have a
way of asking for a specific probe request bitrate,
so we might end up using a bitrate that we don't
advertise as supported. I'll fix that later.
Also add a hexdump printk to hwsim to verify this.
