Dan Williams be8ab90a3a nvdimm/region: Fix default alignment for small regions
[ Upstream commit d9d290d7e6 ]

In preparation for removing BLK aperture support the NVDIMM unit tests
discovered that the default alignment can be set higher than the
capacity of the region. Fall back to PAGE_SIZE in that case.

Given this has not been seen in the wild, elide notifying -stable.
