[Multiple] Knock back Immune Fly aura

Bug description: Flying players that are hit by a knock back effect are dazed and sent to ground.
I see that immune to polymorph aura while flying works but Knock back Immune Fly aura doesn't work (a druid's typhoon will daze and send a flying player to ground removing flight aura)

Proof: ''Wrath-Logo-Small Patch 3.3.0 (08-Dec-2009): Knock back effects no longer dismount players. If on a flying mount, you will be knocked back a short distance before being able to resume flying.
This is likely due an abuse of player knock back abilities in PvP to causing flagged players to fall to their death.''
