IB/mthca: Don't read reserved fields in mthca_QUERY_ADAPTER()
For memfree devices, the firmware QUERY_ADAPTER command does not return vendor_id, device_id, and revision_id; do not return these fields in the QUERY_ADAPTER function for memfree devices. Instead, for memfree devices, initialize the rev_id field of the mthca device via init_node_data (MAD IFC query), as is done in the query_device verb implementation.
