[PATCH v2] x86/platform/uv: Add set of kernel block size for hubless arches

[Mike Travis <mike.travis@hpe.com>]

The commit below added a call to set the block size value that is needed
by the kernel to set the boundaries in the section list.  This was done
for UV Hubbed systems but missed in the UV Hubless setup.  Fix that
mistake by adding that same set call for hubless systems, which support
the same NVRAMS and Intel BIOS, thus the same problem occurs.

Fixes: bbbd2b51a2aa ("x86/platform/UV: Use new set memory block size function")
