ALSA: hda: cs35l56: Put ACPI device after setting companion

acpi_dev_get_first_match_dev() returns a refcounted ACPI device and
callers are expected to balance it with acpi_dev_put().

When no companion is already attached, cs35l56_hda_read_acpi() looks
up an ACPI device and sets it with ACPI_COMPANION_SET(), but leaves
the lookup reference held.

ACPI_COMPANION_SET() does not take ownership of that reference, so
drop it with acpi_dev_put() after attaching the companion.
