[ Upstream commit 2170a0d53bee1a6c1a4ebd042f99d85aafc6c0ea ]
Overwrite retains the security state after completion of operation. Fix
nfit_test to reflect this so that the kernel can test the behavior it is
more likely to see in practice.
Fixes: 926f74802cb1 ("tools/testing/nvdimm: Add overwrite support for nfit_test")
