lvcreate: ensure striped raid region size is at least stripe size
The kernel MD runtime requires region size to be larger than stripe size
on striped raid layouts, thus the dm-raid target's constructor rejects
such request.
This causes e.g. an 'lvcreate --type raid10 -i3 -I4096 -R2048 -n lv vg' to fail.
Avoid failing late in the kernel by enforcing region size to be
larger or equal to stripe size.
