[PATCH AUTOSEL 5.7 163/388] soundwire: slave: don't init debugfs on device registration error

[Sasha Levin]

From: Pierre-Louis Bossart <pierre-louis.bossart at linux.intel.com>

[ 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.
