NFS - fix recent breakage to NFS error handling.
commit 2edb6bc3852c681c0d948245bd55108dc6407604 upstream.

Subject: NFS - fix recent breakage to NFS error handling.
commit 02c24a82187d5a628c68edfe71ae60dc135cd178 made a small and
presumably unintended change to write error handling in NFS.
Previously an error from filemap_write_and_wait_range would only be of
interest if nfs_file_fsync did not return an error. After this commit,
an error from filemap_write_and_wait_range would mean that (the rest of)
nfs_file_fsync would not even be called.
This means that:
1/ you are more likely to see EIO than e.g. EDQUOT or ENOSPC.
2/ NFS_CONTEXT_ERROR_WRITE remains set for longer so more writes are
synchronous.
This patch restores previous behaviour.
