ALSA: hda/tas2781: properly initialize speaker_id for TAS2563

After speaker id retrieval was refactored to happen in tas2781_read_acpi,
devices that do not use a speaker id need a negative speaker_id value
instead of NULL, but no initialization was added to the TAS2563 code path.
This causes the driver to attempt to load a non-existent firmware file name
with a speaker id of 0 ("TAS2XXX38700.bin") instead of the correct file
name without a speaker id ("TAS2XXX3870.bin"), resulting in low volume and
these dmesg errors:

    tas2781-hda i2c-INT8866:00: Direct firmware load for TAS2XXX38700.bin failed with error -2
    tas2781-hda i2c-INT8866:00: tasdevice_dsp_parser: load TAS2XXX38700.bin error
    tas2781-hda i2c-INT8866:00: dspfw load TAS2XXX38700.bin error
    [...]
    tas2781-hda i2c-INT8866:00: tasdevice_prmg_load: Firmware is NULL

Fix this by setting speaker_id to -1 as is done for other models.
