Marcel Holtmann 01d5e44ace Bluetooth: hci_bcm: Handle empty packet after firmware loading
The Broadcom controller on the Raspberry Pi3 sends an empty packet with
packet type 0x00 after launching the firmware. This will cause logging
of errors.

  Bluetooth: hci0: Frame reassembly failed (-84)

Since this seems to be an intented behaviour of the controller, handle
it gracefully by parsing that empty packet with packet type 0x00 and
then just simply report it as diagnostic packet.

With that change no errors are logging and the packet itself is actually
recorded in the Bluetooth monitor traces.
