timekeeping: Fix error code in tk_aux_sysfs_init()

timekeeping: Fix error code in tk_aux_sysfs_init()

commit c7418164b463056bf4327b6a2abe638b78250f13 upstream.

If kobject_create_and_add() fails on the first iteration, then the error
code is set to -ENOMEM which is correct. But if it fails in subsequent
iterations then "ret" is zero, which means success, but it should be
-ENOMEM.

Set the error code to -ENOMEM correctly.
