ALSA: hda: generic: Remove redundant assignment to dac

Browse Source 
Variable dac is set to zero, but this value is never read as it is
overwritten or not used later on, hence it is a redundant assignment
and can be removed.

Clean up the following clang-analyzer warning:

sound/pci/hda/hda_generic.c:1436:4: warning: Value stored to 'dac' is
never read [clang-analyzer-deadcode.DeadStores].
