[PATCH AUTOSEL 4.19 6/6] NFSD: Return nfserr_serverfault if splice_ok but buf->pages have data

[ Upstream commit 06981d560606ac48d61e5f4fff6738b925c93173 ]

This was discussed with Chuck as part of this patch set. Returning
nfserr_resource was decided to not be the best error message here, and
he suggested changing to nfserr_serverfault instead.
