libnvdimm/pmem: Advance namespace seed for specific probe errors
In order to support marking namespaces with unsupported feature/versions disabled, nvdimm core should advance the namespace seed on these probe failures. Otherwise, these failed namespaces will be considered a seed namespace and will be wrongly used while creating new namespaces. Add -EOPNOTSUPP as return from pmem probe callback to indicate a namespace initialization failures due to pfn superblock feature/version mismatch.
