debugfs: debugfs_lookup() should return NULL if not found
Lots of callers of debugfs_lookup() were just checking NULL to see if
the file/directory was found or not. By changing this in ff9fb72bc077
("debugfs: return error values, not NULL") we caused some subsystems to
easily crash.
Fixes: ff9fb72bc077 ("debugfs: return error values, not NULL")
