[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.
