NFS: Fix initialization of nfs_page_array->npages
Commit 8ef9b0b9e1c0 open-coded nfs_pgarray_set(), and left out the initialization of the nfs_page_array's npages. This mistake didn't show up until testing with block layouts, and there shows that all pNFS reads return -EIO. Fixes: 8ef9b0b9e1c0 ("NFS: move nfs_pgarray_set() to open code") Signed-off-by: Benjamin Coddington <bcodding@redhat.com> Cc: stable@vger.kernel.org # 4.12 Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
