mmc: core: Replacing sprintf() with snprintf()



While using the sysfs entry for getting the different bit values
of EXT_CSD register, it is returned by sprintf(). But sprintf() has
been deprecated, that's why replace with safe function snprintf().
By using this patch, PAGE_SIZE(4Kb) is the max number of characters
store in a buffer.
