[ Upstream commit c0e71d6020 ]
When a kernel is configured without CONFIG_DEV_DAX_PMEM_COMPAT, the
compilation of tools/testing/nvdimm fails with:
Building modules, stage 2.
MODPOST 11 modules
ERROR: "dax_pmem_compat_test" [tools/testing/nvdimm/test/nfit_test.ko] undefined!
Fix the problem by calling dax_pmem_compat_test() only if the kernel has
the required functionality.
