Having a transfer more than 32 bits is not all that unlikely. Remove
the annotation.
The unlikely in the IRQ handler can't gain us much. It's not in a
loop, so at most it would save 1 instruction per IRQ, which isn't
much. In fact on the compiler I tested it produced the exact same
code. Remove it too.
