Subject: RDMA/mlx4: Initialize ib_spec on the stack
From: Alaa Hleihel <alaa@xxxxxxxxxxxx>
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: a37a1a428431 ("IB/mlx4: Add mechanism to support flow steering over IB links")
