Log message:
As it was made evident by Olaf 'Rhialto' Seibert in the NetBSD PR 34583,
caching the last cluster in the file before extending it considerably
speeds up further lookups. As a consequence this keeps write speed from
gradually decreasing and provides a measurable (up to 2x) performance
increase. Prompted by the diff from Alexander Polakov, ok miod, krw.
