sound: ASoC: Fix an error path in neo1973_wm8753

The error handling in neo1973_init is incorrect:

* If platform_device_add fails, we go on with the rest of the
  initialization instead of bailing out. Things will break when the
  module is removed (platform_device_unregister called on a device
  that wasn't registered.)

* If i2c_add_driver fails, we return an error so the module will not
  load, but we don't unregister neo1973_snd_device, so we are leaking
  resources.

Add the missing error handling.
