[PATCH v2 4/4] libnvdimm/region: reduce an unnecessary if branch in nd_region_create()

[Zhen Lei]

The "else" branch can only be entered when ndr_desc->flush is NULL. After
replaced "NULL" with "ndr_desc->flush", we will find that the statements
in "if..else.." are the same.

No functional change.
