Subject: [PATCH 076/217] ndctl/test: Fix support for missing dax_pmem_compat
module
The kernel is moving to drop CONFIG_DEV_DAX_PMEM_COMPAT. Update
ndctl_test_init() to not error out if dax_pmem_compat is missing. It seems
that the original implementation of support for missing dax_pmem_compat was
broken, or since that time newer versions of kmod_module_new_from_name() no
longer fail when the module is missing.
