ALSA: emu10k1: minor optimizations

Browse source 
- In snd_emu10k1_look_for_ctl(), evaluate the cheap condition first
- In _snd_emu10k1_{audigy_,}init_efx(), don't use expensive bit setting
  loops to fill arrays
- In snd_emu_proc_ptr_reg_read(), remove useless condition - iobase can
  be only 0 or 0x20
