ALSA: emu10k1: fix E-MU card dock presence monitoring

Browse source

While there are two separate IRQ status bits for dock attach and detach,
the hardware appears to mix them up more or less randomly, making them
useless for tracking what actually happened. It is much safer to check
the dock status separately and proceed based on that, as the old polling
code did.

Note that the code assumes that only the dock can be hot-plugged - if
other option card bits changed, the logic would break.
