ALSA: hda: simplify match functions and remove unreachable return

Browse Source 
hda_bus_match() has an unreachable 'return 1' after an if/else that
covers both branches.  Remove the superfluous return and simplify the
control flow by dropping the else branch.

hdac_codec_match() uses a redundant if/else to return 1 or 0.
Simplify to a single return statement.
