Subject: [PATCH] ndctl/test: Relax dax_pmem_compat requirement

Patch-mainline: v68
Git-commit: b7991dbc22f31d03a38f3ee2dca4446fb55279e3

While there are some tests that require the new "dax-bus" device model,
none of the tests require compatibility mode. Drop the requirement so
the tests work with DEV_DAX_PMEM_COMPAT=n kernels.
