Subject: mm: huge_memory: convert remaining use of sprintf to sysfs_emit and neatening
Convert the only use of sprintf with struct kobject * that the cocci
script could not convert.
Miscellanea:
o Neaten the uses of a constant string with sysfs_emit to use a const
char * to reduce overall object size
