NFSv4.2: Fix detection of "Proxying of Times" server support
According to draft-ietf-nfsv4-delstid-07:
If a server informs the client via the fattr4_open_arguments
attribute that it supports
OPEN_ARGS_SHARE_ACCESS_WANT_DELEG_TIMESTAMPS and it returns a valid
delegation stateid for an OPEN operation which sets the
OPEN4_SHARE_ACCESS_WANT_DELEG_TIMESTAMPS flag, then it MUST query the
client via a CB_GETATTR for the fattr4_time_deleg_access (see
Section 5.2) attribute and fattr4_time_deleg_modify attribute (see
Section 5.2).
Thus, we should look that the server supports proxying of times via
OPEN4_SHARE_ACCESS_WANT_DELEG_TIMESTAMPS.
We want to be extra pedantic and continue to check that FATTR4_TIME_DELEG_ACCESS
and FATTR4_TIME_DELEG_MODIFY are set. The server needs to expose both for the
client to correctly detect "Proxying of Times" support.
