Subject: libnvdimm: fix the clear-error check in nsio_rw_bytes

From: Vishal Verma <vishal.l.verma@intel.com>

commit 7e5a21dfe5524a85705d3bc7b540c849cc13e9a1 upstream.

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.
