[PATCH] net/ice: remove unreachable DCF scheduler branch

[Artem Novikov <naa@amicon.ru>]

Non-leaf node validation rejects any non-NULL WFQ weight mode before
checking the SP priority count. Therefore the later else-if branch
cannot be reached, because wfq_weight_mode is guaranteed to be NULL at
that point.

Remove the dead branch to avoid keeping an impossible validation path in
the DCF scheduler parameter checks.
