dcadec: treat all 2-channel modes as Stereo in dca_downmix.
...
The check for (prim_channels > 2) before calling dca_downmix made these
cases unreachable, but now 2.1 layouts will go through the downmix code.
Having dual mono, Lt/Rt and sum-difference layouts print errors when
regular Stereo doesn't seems pointless.

dca: improve default stereo downmix coefficients.
...
Previous coefficients were producing a non-normalized, incorrect Lt/Rt downmix.
The new coefficients produce a standard Lo/Ro downmix with 3dB attenuation.
This should match the typical default coefficients used by DTS encoders.
