[SYSTEMDS-3417] Fix integer overflow in fast-buffered-input-stream

This patch fixes an integer overflow---encountered when deserializing
large, multi-array matrix blocks---where the individual chunks are close
to INT_MAX. In such cases, the integer loop variable i+=_bufflen/8
did overflow on the increment by += (bufflen (default 8K) div 8),
running into index-out-of-bounds with negative indexes.
