Subject: [PATCH v3 net-next 06/11] ice: remove redundant checks in ice_change_mtu

dev_validate_mtu checks that mtu value specified by user is not less
than min mtu and not greater than max allowed mtu. It is being done
before calling the ndo_change_mtu exposed by driver, so remove these
redundant checks in ice_change_mtu.
