Obtain the number of channels for the Input Terminal from the
Logical Cluster Descriptor. This achieves a useful minimal parsing

Sorry about this. I just spotted that I should have used the helper
function I added to access d->wClusterDescrID
`uac3_mixer_unit_wClusterDescrID`.
I got the sparse warning for the endianess and realized that. I'll
resend this one patch.
