Bluetooth: Add hdev parameter to hdev->send driver callback
Instead of masking hdev inside the skb->dev parameter, hand it
directly to the driver as a parameter to hdev->send. This makes
the driver interface more clear and simpler.
This patch fixes all drivers to accept and handle the new parameter
of hdev->send callback. Special care has been taken for bpa10x
and btusb drivers that require having skb->dev set to hdev for
the URB transmit complete handlers.
