nfsd: encoders mustn't use unitialized values in error cases
commit f961e3f2acae94b727380c0b74e2d3954d0edf79 upstream.
In error cases, lgp->lg_layout_type may be out of bounds; so we
shouldn't be using it until after the check of nfserr.
This was seen to crash nfsd threads when the server receives a LAYOUTGET
request with a large layout type.
GETDEVICEINFO has the same problem.
