RDMA/mlx4: Initialize ib_spec on the stack

Browse source 
commit c08cfb2d8d78bfe81b37cc6ba84f0875bddd0d5c upstream.

Initialize ib_spec on the stack before using it, otherwise we will have
garbage values that will break creating default rules with invalid parsing
error.

Fixes: a37a1a4284 ("IB/mlx4: Add mechanism to support flow steering over IB links")
