IB/core: Fix query port failure in RoCE
Currently ib_query_port always attempts to to read the subnet prefix by
calling ib_query_gid(). For RoCE/iWARP there is no subnet manager and no
subnet prefix. Fix this by querying GID[0] only for IB networks.
Fixes: fad61ad4e755 ('IB/core: Add subnet prefix to port info')
