qede: fix general protection fault may occur on probe

Orabug: 25477939

The recent introduction of qedr driver support in qede causes a GPF when probing the driver in a server without a RoCE enabled QLogic NIC. This fix avoids using an uninitialized pointer in such a case. Caught by the kernel test robot.
