ASoC: tas5720: add missing unwind goto in tas5720_codec_probe

Smatch complains that missing unwind goto in tas5720_codec_probe.

When tas5720 has an invalid devtype, it is expected to invoke
regulator_bulk_disable to handle the failure. But the default
option return an error code directly. Fix it by reusing the
probe_fail label.
