entity_association_tree: Keep tree always updated
This commit keeps the entity association tree updated across Host
reboots. It deletes the Host entries from the entity associaton
tree when Host is powered off.
Without this fix the entity association tree keeps on growing with
duplicate Host entries during each power on(PDR exchange) resulting
a crash of pldm daemon after few power on-off sequence
