Removed values were default.

This is wrong for uid_attribute. You can see it when you run "make
test", which fails with your patch. It's also wrong for
retain_hwhandler, but that entry should indeed be removed, because
keeping it there is misleading at best. hwhandlers have no meaning for
NVMe, and retain_hwhandler is enforced to be true an all kernels since
4.3.

Check ANA, else fall back to CONST(multibus).
