Avoid large numbers of refresh_time cache entries

Commit 729896467e3c77904666019d6cbbda583ae49b95 amended
kg_cred_time_to_refresh() to attempt a refresh from a client keytab
when creds are close to expiration, even if no refresh_time config
entry is set (as would be the case if the creds were acquired from a
client keytab in the first place).  The added conditional sets a
refresh_time config entry, which is unhelpful as it has no
corresponding check for one.  kg_cred_time_to_refresh() is called
before can_get_initial_creds(), so we add a config entry on every
acquire_cred call when the creds are expired or close to expired, even
with no accessible keytab.  Remove the set_refresh_time() call to
avoid this inefficient behavior.
