Bluetooth: Remove return value from hci_send_frame() function
The return value of hci_send_frame() is never checked. So just make
this function void and print an error when the hdev->send driver
callback returns a negative value.
Having the error printed is actually an improvement over the
current situation where any driver error just gets ignored.
