Subject: [PATCH] Do not try to normalize size for zero size device factories

Factories with zero size are special cases for adjusting container
size after removing a device for it. We don't want to change size
of the factory in this case.
The recent change of filesystem minimal size to 2 MiB resulted
in changing of size of these factories from 0 to 2 MiB which
caused the "adjusting factory" to create a new LV after removing
one from the container.

Resolves: rhbz#1743753
