Since the debugfs_create_dir() never returns a null pointer, checking
the return value for a null pointer is redundant. Remove this check
since debugfs_create_file can handle IS_ERR pointers. At the same time,
debugfs_create_dir returns ERR_PTR (-ENODEV) by default when
CONFIG_DEBUG_FS=N, so there is no need for CONFIG_DEBUG_FS macro
isolation.

v1 -> v2: Remove this check since debugfs_create_file can handle IS_ERR
pointers. And drop the ifdef CONFIG_DEBUG_FS statement.
v1:
