Drop dirent ref when releasing dirent

During a readdir, the dirents in a chunk take a ref on the entry they
point to, so that the entry can't be reaped until the chunk has been
processed.  Make sure that, if a dirent is released while it still has a
ref, we drop the ref.  Otherwise, under heavy create/delete/readdir
load, we can leak refs to entries.
