Fix bz608048

The same region size is used for both mirror volume and mirrored
log volume, but when physical extent size is bigger than region size,
the size of mirror leg for mirrored log is smaller than the region size
and lvcreate command fails.

This patch adjusts a region size of mirrored log to a smaller value of
region size or physical extent size.
