zcryptstats: Add note about loading kernel module chsc_sch

Browse Source 
Dependent on kernel config option CHSC_SCH the device node /dev/chsc may
exist per default or not. In case the kernel is built with CHSC_SCH=M,
then the device driver is built as separate kernel module, and must
therefore be loaded using modprobe chsc_sch to make device node /dev/chsc
available.
