Bluetooth: Only keep controller up after init if powered on

When a new controller gets added to the system, it needs to be brought
up briefly to read basic information like features, BD_ADDR etc. and
after a timeout it will be brought back down.

The only command that should overwrite this timeout is the set power
command from the management interface. Just reading the controller
list or information is not a good reason to keep the controller up.

Bluetooth: Fix issue with shared SKB between HCI raw socket and driver

Any HCI raw socket gets a copy of each SKB that is either received or
send via the Bluetooth subsystem. The raw socket uses SKB clones to
send out data, but the problem is that it needs to add an extra packet
type byte in front of it. And some drivers need to also add an extra
header before submitting the packet.

So far this all worked magically fine since all of the drivers and the
raw sockets are adding the same byte at the same location. But that is
by pure coincidence. Since the data of cloned SKBs is shared, this means
that the raw socket and driver kept writing into the shared data area.

To fix this the only safe way is if the HCI raw socket creates a copy of
the SKB before sending it out. To not always copy all SKBs around, the
copy is only created once and only after any of the HCI filter checks
succeeded.
