ksmbd: fix missing RDMA-capable flag for IPoIB device in ksmbd_rdma_capable_netdev()

Browse source

[ Upstream commit ecce70cf17 ]

Physical ib_device does not have an underlying net_device, thus its
association with IPoIB net_device cannot be retrieved via
ops.get_netdev() or ib_device_get_by_netdev(). ksmbd reads physical
ib_device port GUID from the lower 16 bytes of the hardware addresses on
IPoIB net_device and match its underlying ib_device using ib_find_gid()
