3.16.40-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Jack Morgenstein <jackm@xxxxxxxxxxxxxxxxxx>

commit 44b911e77793d686b481608770d0c55c18055ba0 upstream.

In procedure mlx4_flow_steer_promisc_add(), several fields
were left uninitialized in the rule structure.
Correctly initialize these fields.
