IB/mlx4: When no DMFS for IPoIB, don't allow NET_IF QPs
commit 1f22e454df2eb99ba6b7ace3f594f6805cdf5cbc upstream.
According to the firmware spec, FLOW_STEERING_IB_UC_QP_RANGE command is
supported only if dmfs_ipoib bit is set.
If it isn't set we want to ensure allocating NET_IF QPs fail. We do so
by filling out the allocation bitmap. By thus, the NET_IF QPs allocating
function won't find any free QP and will fail.
Fixes: c1c98501121e ('IB/mlx4: Add support for steerable IB UD QPs')
