[PATCH] loongarch: fix debugfs_create_dir error checking

[mirimmad]

From: Immad Mir <mirimmad17@xxxxxxxxx>

The debugfs_create_dir returns ERR_PTR incase of an error and the
correct way of checking it by using the IS_ERR inline function, and
not the simple null comparision. This patch fixes this.
