ALSA: emu10k1: fix SNDRV_EMU10K1_IOCTL_SINGLE_STEP 

- Use correct address limit for Audigy
- Use the right constant to actually make a step on Audigy
- Don't store *_DBG_STEP and the address in emu->fx8010.dbg, as
  otherwise unrelated operations would make steps, too

This is untested. as10k1 was never ported to Audigy anyway.
