The ioremap passed as argument to __nfit_test_ioremap can be a macro so
it cannot be passed as function argument. Make __nfit_test_ioremap into
a macro so that ioremap can be passed as untyped macro argument.

Fixes: 6bc756193ff6 ("tools/testing/nvdimm: libnvdimm unit test infrastructure")

The fallback_fn was passed around to start with, and ioremap was already
a define when this was merged.

Looks reasonable to me and passes tests, applied.
