ASoC: acpi: fix machine driver selection based on quirk
commit 5c256045b87b8aa8e5bc9d2e2fdc0802351c1f99 upstream.
The ACPI/machine-driver code refactoring introduced in 4.13 introduced
a regression for cases where we need a DMI-based quirk to select the
machine driver (the BIOS reports an invalid HID). The fix is just to
make sure the results of the quirk are actually used.
Fixes: 54746dabf770 ('ASoC: Improve machine driver selection based on quirk data')
