RDMA/cxgb3: Enforce required firmware
The cxgb3 NIC driver can handle more firmware versions than iw_cxgb3,
and since commit 8207befa ("cxgb3: untie strict FW matching") cxgb3
will load with firmware versions that iw_cxgb3 can't handle. The FW
major number indicates a specific interface between the FW and
iw_cxgb3. Thus if the major number of the running firmware does not
match the required version compiled into iw_cxgb3, then iw_cxgb3 must
not register that device.
