[PATCH] ALSA: emu10k1: clarify various fx8010.*_mask fields
extin_mask and extout_mask are used only by the SbLive! microcode, so they have no effect on Audigy.
Eliminate fxbus_mask entirely, as it wasn't actually used for anything.
As a drive-by, remove the pointless pad1 field from struct snd_emu10k1_fx8010 - it is not visible to user space, so it has no binary compatibility constraints.
