[pnfs] [PATCH] filelayout_encode_layoutlist_item encodes 4 bytes of garbage

[Ricardo Labiaga]

The encoding of dev_layout_type (32 bits) was removed from
filelayout_encode_layoutlist_item() by commit:
	21ea95d098e20662992c9e4f975ca998a3027878.

The returned length needs to also be updated.
This change reduces the returned length by 4 bytes to avoid XDR
encoding a hole with trash in the buffer.
