[PATCH v2] loongarch: fix debugfs_create_dir error checking

From: mirimmad
Date: Sun May 14 2023 - 02:45:15 EST


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_OR_NULL inline function, and
not the simple null comparision. This patch fixes this.
