libnvdimm: fix the clear-error check in nsio_rw_bytes

Browse Source 
commit 7e5a21dfe5 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.

Fixes: 3ae3d67ba7 ("libnvdimm: add an atomic vs process context flag to rw_bytes")
