Subject: [PATCH] tools/testing/nvdimm: Fix compilation failure without
 CONFIG_DEV_DAX_PMEM_COMPAT

References: bsc#1159523
Patch-mainline: v5.7-rc1
Git-commit: c0e71d602053e4e7637e4bc7d0bc9603ea77a33f

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.
