ALSA: emu10k1: simplify interrupt handler, part 2

Remove weird INTE_* clearing code. The bits were a subset of the
actually handled interrupts, which kind of contradicted the stated
purpose. I suppose it would make sense to complete the set and negate
it, but interrupts being enabled out of the blue is neither something
that happens a lot, nor should it result in just one error message, IMO.
