Subject: [PATCH v1] thermal/debugfs: Remove unnecessary debugfs_create_dir() error check in thermal_debug_init()

This patch removes the debugfs_create_dir() error checking in
thermal_debug_init(). Because the debugfs_create_dir() is developed
in a way that the caller can safely handle the errors that
occur during the creation of DebugFS nodes.
