libnvdimm, pmem: Fix memcpy_mcsafe() return code handling in nsio_rw_bytes()
Commit 60622d68 "x86/asm/memcpy_mcsafe: Return bytes remaining" converted callers of memcpy_mcsafe() to expect a positive 'bytes remaining' value rather than a negative error code. The nsio_rw_bytes() conversion failed to return success. The failure is benign in that nsio_rw_bytes() will end up writing back what it just read.
