Dmitry Ilvokhin 813e5598e5 nvdimm: Convert nvdimm_bus guard to class ...

The nvdimm_bus guard accepts NULL and skips locking when NULL is passed.
Convert from DEFINE_GUARD() to DEFINE_CLASS() + DEFINE_CLASS_IS_GUARD().

This is a preparatory change for making DEFINE_GUARD() constructors
__nonnull_args(). nvdimm_bus legitimately passes NULL, so it must be
adjusted to avoid a compile error.

No functional change.
