TS-5065: Fix RefCountCache iterator invalidation.
Removing items from the TSHashMap invalidates the iterator because the
linked list pointers are embedded in the hash node, so we can't do that
while clearing. Instead, deallocate and remove each entry explicitly.

TS-5066: Fix HostDB memory leaks on serialization failure.
If the serializer fails to write the partition, the copied entries were
being leaked. Clean up the cache entry allocation to centralize the
pain of it and allow both the cache and the serializer to share the same
allocation and free helpers.
