[PATCH net 1/5] drivers: net: ice: fix devlink parameters get without irdma

[Tony Nguyen <anthony.l.nguyen@intel.com>]

From: Nikolay Aleksandrov <nikolay@nvidia.com>

If CONFIG_IRDMA isn't enabled but there are ice NICs in the system, the
driver will prevent full devlink dev param show dump because its rdma get
callbacks return ENODEV and stop the dump. For example:
 $ devlink dev param show
 pci/0000:82:00.0:
   name msix_vec_per_pf_max type generic
     values:
       cmode driverinit value 2
   name msix_vec_per_pf_min type generic
     values:
       cmode driverinit value 2
 kernel answers: No such device

Returning EOPNOTSUPP allows the dump to continue so we can see all devices'
devlink parameters.
