ALSA: hda/tas2781: Fix the ld issue reported by kernel test robot

After commit 9fa6a69 ("ALSA: hda/tas2781: Remove tas2781_spi_fwlib.c
and leverage SND_SOC_TAS2781_FMWLIB")created a separated lib for i2c,
However, tasdevice_remove() used for not only for I2C but for SPI being
still in that lib caused ld issue.
All errors (new ones prefixed by >>):
>> ld.lld: error: undefined symbol: tasdevice_remove
   >>> referenced by tas2781_hda.c:33 (sound/pci/hda/tas2781_hda.c:33)
   >>>               vmlinux.o:(tas2781_hda_remove)
To fix this issue, the implementation of tasdevice_remove was moved from
tas2781-comlib-i2c.c to tas2781-comlib.c.
