The admin node ask the partition table itself, so don't send it anymore.

When a storage node died, leaving the pt in a non-operational state, this now
nicely handled at the connection closure (see previous commit), so it is no more
usefull to check the pt status at temporarily state expiration.
Add an comment to fix a bug just found.
