net/mlx4_core: Fixes for VF / Guest startup flow
- pass the following parameters:
- firmware version (added QUERY_FW paravirtualization for that)
- disable Blueflame on slaves. KVM disables write combining on guests,
and we get better performance without BF in this case. (This requires
QUERY_DEV_CAP paravirtualization, also in this commit)
- max qp rdma as destination
- get rid of a chunk of "if (0)" dead code
