Trivial cleanups & 64-bit fixes for donauboe.c

[Pavel Machek <pavel@ucw.cz>]

Hi!

donauboe uses __u32; this is kernel code, you are allowed to use u32
which is less ugly. ASSERT() is pretty ugly. I made it 64-bit clean,
and if it is outside 32-bit range, it BUG()s. Not ideal, but better
than not compiling.
