soundwire: slave: don't init debugfs on device registration error

2020-06-24T15:50:23+00:00

[ Upstream commit 8893ab5e8ee5d7c12e0fc1dca4a309475064473d ] The error handling flow seems incorrect, there is no reason to try and add debugfs support if the device registration did not succeed. Return on error.
