The ESXi NFSv4.1 client will generate warning messages when the reason for
not issuing a delegation is two. Two refers to a resource limit and I do
not see why it would be considered invalid. However it probably was not the
best choice of reason for not issuing a delegation.
This patch changes the reasons used to ones that the ESXi client doesn't
complain about. This change does not affect the FreeBSD client and does
not appear to affect behaviour of the Linux NFSv4.1 client.
RFC5661 defines these "reasons" but does not give any guidance w.r.t. which
ones are more appropriate to return to a client.
