libnvdimm: fix the clear-error check in nsio_rw_bytes 

A leftover from the 'bandaid' fix that disabled BTT error clearing in
rw_bytes resulted in an incorrect check. After we converted these checks
over to use the NVDIMM_IO_ATOMIC flag, the ndns->claim check was both
redundant, and incorrect. Remove it.
