stasic.c: Fix printf format type mismatches with arguments.

stasic.c: Fix printf format type mismatches with arguments.

An int64_t is not likely the same size as a long.

* Changed the int64_t values in the statistics structs to longs so casting
is not necessary when generating the formatted CLI output.  The offending
members did not need to be int64_t anyway as they were only set by an int
type variable which was already truncating bits.

* Reordered the statistics structs to reduce potential padding bytes.
