dax/bus.c: replace several sprintf() with sysfs_emit()

Browse source 
There were several places where drivers/dax/bus.c uses 'sprintf' to print
sysfs data.  Since a sysfs_emit() helper is available specifically for
this purpose, replace all the sprintf() usage for sysfs with sysfs_emit()
in this file.
