Subject: [PATCH] Bluetooth: Enforce providing hdev->send driver callback

The hdev->send driver callback is mandatory to be provided by a driver
before calling hci_register_dev. So enforce it and return EINVAL in
case it is not available.

All existing drivers are providing this callback anyway, so this is
just an extra sanity check.
