NFS: Do not report writeback errors in nfs_getattr() 

commit d19e0183a88306acda07f4a01fedeeffe2a2a06b upstream.

The result of the writeback, whether it is an ENOSPC or an EIO, or
anything else, does not inhibit the NFS client from reporting the
correct file timestamps.

Fixes: 79566ef018 ("NFS: Getattr doesn't require data sync semantics")
