ALSA: core: Fix SSID quirk lookup for subvendor=0 

Some weird devices set the codec SSID vendor ID 0, and
snd_pci_quirk_lookup_id() loop aborts at the point although it should
still try matching with the SSID device ID.  This resulted in a
missing quirk for some old Macs.

Fix the loop termination condition to check both subvendor and
subdevice.
