Don't send update_lru messages when disabled

The couchdb.update_lru_on_read setting controls whether couch_server
uses read requests as LRU update triggers. Unfortunately, the messages
for update_lru on reads are sent regardless of whether this is enabled
or disabled. While in principle this is harmless, and overloaded
couch_server pid can accumulate a considerable volume of these messages,
even when disabled. This patch prevents the caller from sending an
update_lru message when the setting is disabled.
