--------------------------------

[ Upstream commit c9ed0a70 ]

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: a0fb3726 ("Bluetooth: Use Set ext adv/scan rsp data if controller supports")
