RDMA/rxe: Set sys_image_guid to be aligned with HW IB devices

From: Zhu Yanjun <[email protected]>

The RXE driver doesn't set sys_image_guid and user space applications see zeros. This causes to pyverbs tests to fail with the following traceback, because the IBTA spec requires to have valid sys_image_guid.

Traceback (most recent call last):
File "./tests/test_device.py", line 51, in test_query_device
self.verify_device_attr(attr)
File "./tests/test_device.py", line 74, in verify_device_attr

     assert attr.sys_image_guid != 0

In order to fix it, set sys_image_guid to be equal to node_guid.

Before:
5: rxe0: ... node_guid 5054:00ff:feaa:5363 sys_image_guid 0000:0000:0000:0000

After:
5: rxe0: ... node_guid 5054:00ff:feaa:5363 sys_image_guid 5054:00ff:feaa:5363
