gpio: sloppy-logic-analyzer: Check for error code from devm_mutex_init() call
[ Upstream commit 90bad749858cf88d80af7c2b23f86db4f7ad61c2 ]
Even if it's not critical, the avoidance of checking the error code
from devm_mutex_init() call today diminishes the point of using devm
variant of it. Tomorrow it may even leak something. Add the missed
check.
