In LVM2/tools/lvcreate.c:_lvcreate there is a missing check for lp->corelog when
creating mirrors, which causes a call to create_mirror_log() even when core
logging was requested.
This prevents users from being able to create mirrors with core logs (single
machine or cluster).
Users are still able to lvconvert to/from mirrors with core logs, and recovery
scenarios are unaffected.
