Bluetooth: Fix Set Extended (Scan Response) Data
These command do have variable length and the length can go up to 251,
so this changes the struct to not use a fixed size and then when
creating the PDU only the actual length of the data send to the
controller.
Fixes: a0fb3726ba551 ("Bluetooth: Use Set ext adv/scan rsp data if controller supports")
