ALSA: emu10k1: fix+optimize E-MU stereo capture DSP code
Presumably, JDC added the seemingly superfluous indirection over the
temporary register because without it he'd get only zero readings.
However, switching the X and Y operands (or using EMU32 as the A
operand in the temporary load) works just fine. Presumably a DSP bug?
The original code was also actually buggy, though: both channels used
the left volume control.
