Disallow 'mirrored' log for cluster mirrors.

Browse Source 
Git commit ID 0864378250 was meant to disallow
'mirrored' logs for cluster mirrors.  However, when add_mirror_log is used
to create the log (as is now the case when using 'lvcreate' or converting only
the log) the check is bypassed.

This patch adds the check to add_mirror_log.
