show-expire: Recreate openssl-easyrsa.cnf (Temp) in read_db()

The temp-session is recreate for each record read, otherwise the
temp-file counter grows as the database grows.  This way, temp-files
are created as if each record is a separate instance of 'easyrsa'.

Recreate the openssl-easyrsa.cnf (Temp) when the temp-session
is recreated.
