osd_type: use SERVER_TENTACLE for fixing the pg_pool_t dencoding

The Nitzan's fix has made into Squid, so just replace `SERVET_SQUID`
with `SERVER_TENTACLE`. The commit was never exposed, so it should
be perfectly fine to just bump up. Doing this in separate commit to
keep the boundaries between changes from 2 authors.
