Merge branch 'mlx4_bond_notify'

Or Gerlitz says:

====================
bonding and mlx4 fixes for the HA/LAG support and mlx4 reset flow

There are two fixes to the boding + mlx4 HA/LAG support from Moni and a patch from Yishai
which does further hardening of the mlx4 reset support for IB kernel ULPs.
