RDMA/providers: Simplify query_gid callback of RoCE providers
ib_query_gid() fetches the GID from the software cache maintained in ib_core for RoCE ports. Therefore, simplify the provider drivers for RoCE to treat query_gid() callback as never called for RoCE, and only require non-RoCE devices to implement it.
