iwlagn: use huge command for beacon
When testing some new P2P code, Angie found that the
driver might crash because the beacon command ended
up being bigger than a regular command. This is quite
obvious -- a normal command is limited to roughly 360
bytes but a beacon may be much larger of course.
To fix this, use the huge command buffer.
