Bluetooth: Add support for custom event terminated commands
This patch adds support for having commands within HCI requests that do
not result in a command complete but some other event. This is at least
needed for some vendor specific commands to be issued in the
hdev->setup() procecure, but might also be useful for other commands.
The way that the support is implemented is by extending the skb control
buffer to have a field to indicate that the command is expected to
terminate with a special event. After sending the command each received
event can then be compared against this field through hdev->sent_cmd.
