memory tier, sysfs: rename attribute "nodes" to "nodelist"

In sysfs, we use attribute name "cpumap" or "cpus" for cpu mask and
"cpulist" or "cpus_list" for cpu list.  For example, in my system,

 $ cat /sys/devices/system/node/node0/cpumap
 f,ffffffff
 $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus
 0,00100004
 $ cat cat /sys/devices/system/node/node0/cpulist
 0-35
 $ cat /sys/devices/system/cpu/cpu2/topology/core_cpus_list
 2,20

It looks reasonable to use "nodemap" for node mask and "nodelist" for
node list.  So, rename the attribute to follow the naming convention.
