nfsd4: fix error return when pseudoroot missing
We really shouldn't hit this case at all, and forthcoming kernel and
nfs-utils changes should eliminate this case; if it does happen,
consider it a bug rather than reporting an error that doesn't really
make sense for the operation (since there's no reason for a server to be
accepting v4 traffic yet have no root filehandle).
Also move some exp_pseudoroot code into a helper function while we're
here.
