[PATCH] EDAC/mc_sysfs: add missing newlines when printing 'max(dimm)_location'

[Xiongfeng Wang]

When I cat 'max_location' and 'dimm_location' by sysfs, it displays as
follows. It's better to add a newline for easy reading.

[root@localhost /]# cat /sys/devices/system/edac/mc/mc0/max_location
memory 3 [root@localhost /]# cat /sys/devices/system/edac/mc/mc0/dimm0/dimm_location
memory 0 [root@localhost /]#
