[Bluetooth] Eliminate checks for impossible conditions in IRQ handler
Our info structure and info->hdev is always passed to the IRQ handler, so we don't have to worry about these checks in every interrupt. Leave a BUG_ON() just to help unwary programmers, but these could probably be removed as well. Signed-off-by: Jeff Garzik <jgarzik@redhat.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
