common/buffer: switch crc cache to single pair instead of map

Most bufferptrs have just one entry in their caches, so it makes
perfect sense to store just that. As population and destruction of
std::map isn't free, it yields noticeable perf increase, around 12%
in case of bufferptrs containing just 4k of data, with more as the
bufferptrs get smaller.
