It's basically harmless, and should be gone if you update to the current
CVS JFFS2 code.
A while ago, I implemented a garbage-collection optimisation; if a node
is expected to be identical when we write out a replacement, we can
avoid decompressing and recompressing it if we just copy the whole thing
intact. So I start keeping track of such 'pristine' nodes which were an
optimal representation of their data... and that message warns me of one
case where such a node marked REF_PRISTINE but shouldn't have been.
