ALSA: hda - Fix invalid connections in VT1802 codec

commit ef4da45828603df57e5e21b8aa21a66ce309f79b upstream.

VT1802 codec provides the invalid connection lists of NID 0x24 and
0x33 containing the routes to a non-exist widget 0x3e.  This confuses
the auto-parser.  Fix it up in the driver by overriding these
connections.
