Subject: [PATCH net v1] ice: do not reserve resources for RDMA when disabled

From: Jesse Brandeburg <jbrandeb@...nel.org>

If the CONFIG_INFINIBAND_IRDMA symbol is not enabled as a module or a
built-in, then don't let the driver reserve resources for RDMA.

Do this by avoiding enabling the capability when scanning hardware
capabilities.

Fixes: d25a0fc41c1f ("ice: Initialize RDMA support")
