NFS: Fix initialization of nfs_page_array->npages

Commit 8ef9b0b9e1 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: 8ef9b0b9e1 ("NFS: move nfs_pgarray_set() to open code")
