ALSA: emux: fix init of patch_info.truesize in load_data()

The field is explicitly documented to be initialized by the driver
(which it actually is). Also, using patch_info.size would be actually
wrong for 16-bit data, as one field counts samples, while the other
counts bytes.

load_guspatch() already did it right.
