[PATCH v2] ALSA: emu10k1: minor optimizations

[Oswald Buddenhagen <oswald.buddenhagen@xxxxxx>]

- 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

Signed-off-by: Oswald Buddenhagen <oswald.buddenhagen@xxxxxx>

v2:
- fix fill sizes for sblive by using the previous hard-coded numbers.
  it might be a good idea to introduce constants for that, but that's
  for another patch.
