NFS: Do not report writeback errors in nfs_getattr()

Browse Source 
[ Upstream commit d19e0183a8 ]

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")
