[PATCH iwl-net 3/4] ice: support RDMA on 4+-port E830 devices

[Aleksandr Loktionov <aleksandr.loktionov@intel.com>]

From: Lukasz Czapnik <lukasz.czapnik@intel.com>

E810 and E82X devices do not support RDMA on configurations with more
than 4 ports. This limitation does not apply to E830 devices, which
have a different hardware design and support RDMA regardless of the
port count.

Narrow the RDMA capability disable condition to skip E830 devices.

Fixes: ba1124f58afd ("ice: Add E830 device IDs, MAC type and registers")
