arm64: mm: improve the mem-offline device node availability check

Browse source 
Even if we use status = "disabled" in mem-offline node, still the
update_memory_limit() will go and update memory_limit variable and
thus the removed memory is never added to system as the
mem-offline driver is disabled. Correct this logic.
