cluster/dht: Make optimal usage of buffer provided with readdir(p)
dht_readdirp must unwind with list of entries only after
the entire buffer requested by kernel is filled to avoid
extra syscalls occuring when returning partially filled
buffer. Also wind readdir call to next subvol on reaching
EOD for directory on that subvol to avoid extra network call.
