mm: use sysfs_emit for struct kobject * uses

Patch series "mm: Convert sysfs sprintf family to sysfs_emit", v2.

Use the new sysfs_emit family and not the sprintf family.

This patch (of 5):

Use the sysfs_emit function instead of the sprintf family.

Done with cocci script as in commit 3c6bff3cf988 ("RDMA: Convert sysfs
kobject * show functions to use sysfs_emit()")
