When a creation of mirrored LV fails during its course,
mirror log LV is left unremoved.
The patch removes the log LV if error occurs after commiting it.
# dmsetup create --notable testvg-lv0_mlog
# lvcreate -l1 -m1 -nlv0 testvg
device-mapper: create ioctl failed: Device or resource busy
Aborting. Failed to activate mirror log. Remove new LVs and retry.
Failed to create mirror log.
# lvs -a
LV VG Attr LSize Origin Snap% Move Log Copy%
lv0_mlog testvg -wi-d- 4.00M
Thanks,
