powerpc/pseries: Fix error return value in cmm_mem_going_offline() cmm_mem_going_offline() is (only) called from cmm_memory_cb(), which sends the return value through notifier_from_errno(). The latter expects 0 or -errno (notifier_to_errno(notifier_from_errno(x)) is 0 for any x >= 0, so passing a positive value cannot make sense). Hence negate ENOMEM.
