libnvdimm: allow legacy (e820) pmem region to clear bad blocks
Bad blocks can be injected via /sys/block/pmemN/badblocks. In a situation where legacy pmem is being used or a pmem region created by using memmap kernel parameter, the injected bad blocks are not cleared due to nvdimm_clear_poison() failing from lack of ndctl function pointer. In this case we need to just return as handled and allow the bad blocks to be cleared rather than fail.
