ALSA: hda/tas2781: Fix device-0 reset issue and handle -EXDEV in block data processing

Fix reset for device-0:‌ In older projects (e.g., Merino), the hardware
reset pin for the first SPI device (device-0) is ineffective, causing
initialization failures. Added a software reset sequence for device-0
to ensure proper initialization.

‌Handle -EXDEV correctly:‌ When processing block data, if the data does
not belong to the current SPI device, the driver returned -EXDEV.
This error code is now ignored to allow the driver to continue iterating
through the block data and correctly calculate the total block size.
