ndtest: Cleanup all of blk namespace specific code

With the nd_namespace_blk and nd_blk_region infrastructures being removed,
the ndtest still has some references to the old code. So the
compilation fails as below,

../tools/testing/nvdimm/test/ndtest.c:204:25: error: ‘ND_DEVICE_NAMESPACE_BLK’ undeclared here (not in a function); did you mean ‘ND_DEVICE_NAMESPACE_IO’?
  204 |                 .type = ND_DEVICE_NAMESPACE_BLK,
      |                         ^~~~~~~~~~~~~~~~~~~~~~~

  630 |                 ndbr_desc.enable = ndtest_blk_region_enable;
      |                                    ^~~~~~~~~~~~~~~~~~~~~~~~

  631 |                 ndbr_desc.do_io = ndtest_blk_do_io;
      |                                   ^~~~~~~~~~~~~~~~
      |                                   ndtest_blk_mmio

The current patch removes the specific code to cleanup all obsolete
references.
