ipaclient: ipaclient_fix_ca also needs krb_name parameter

With the fix to defer creating the final krb5.conf on clients a bug has
been introduced with ipaclient_fix_ca: The krb_name parameter that
points to the temporary krb5 configuration was not added to the module

Without this the server affinity is broken for allow_repair and additionally
ipaclient_fix_ca could fail if krb5 configuration needs to be repraied
and also CA needs to be fixed.

The krb_name parameter has been added to ipaclient_fix_ca and is also
properly set in tasks/install.yml.
