libnvdimm: move ->module to struct nvdimm_bus_descriptor
Let the provider module be explicitly passed in rather than implicitly assumed by the module that calls nvdimm_bus_register(). This is in preparation for unifying the nfit and nfit_test driver teardown paths. Reviewed-by: Lee, Chun-Yi <jlee@suse.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
