The function setup_tsb_params has exactly one caller tsb_grow. The function tsb_grow passes in a tsb_bytes value that is between 8192 and 1048576 inclusive, and is guaranteed to be a power of 2. The function setup_tsb_params verifies this property with a switch statement and then prints an error and causes the task to exit if this is not true. In practice that print statement can never be reached because tsb_grow never passes in a bad tsb_size. So if tsb_size ever gets a bad value that is a kernel bug. So replace the do_exit which is effectively an open coded version of BUG() with an actuall call to BUG(). Making it clearer that this is a case that can never, and should never happen.
